Story highlights ISIS releases a video showing the beheading of a man it says was a Russian spy 
 
 The captive's killer tells Russians, " We will kill your sons ... for each son you killed here" 
 
 (CNN) ISIS released video Wednesday showing the beheading of a man it claims joined the terrorist group but was in fact a Russian spy, as well as a message chastising Russian President Vladimir Putin and threatening his country's citizens. 
 
 As the captive kneels before him in an orange jumpsuit, his killer says in Russian that the airstrikes ordered by Putin against the Islamist extremist group has "made us understand that we are doing right thing" by continuing their fight. 
 
 He then addresses the Russian people, saying, "You will not find peace in your homes. We will kill your sons ... for each son you killed here. And we will destroy your homes for each home you destroyed here."

 CNN could not immediately verify the authenticity of the video, much less the ISIS claim that the man beheaded was a Russian spy. CNN also was unable to immediately obtain a comment from the Russian government about whether it believes the video shows a Russian citizen being killed. 
 
 But if the video is authentic, it joins a growing catalog of atrocities in which the terror group has broadcast the killing of one or more captives and paired it with menacing messages.

 Islamic State (ISIS) released a new scare video Wednesday, this time targeting the Russians. 
 
 The video, entitled "You Shall be Disappointed and Humiliated O Russians," shows the beheading of an alleged Chechen spy - a 23 year-old who admits on camera to passing along information to Moscow from Syria and Iraq about the 605 Russian citizens who left to join the jihadists. 
 
 The "spy" added that the Russians are having difficulty keeping track of the foreign nationals, due to the common practice of changing names upon joining the organization. 
 
 The terrorist speaks in Russian before decapitating his victim, stating, "[Russian President Vladimir] Putin, you dog, we attacked [Syrian President Bashar] Assad prior to your arrival as well as the Americans and their allies - we will also attack you." 
 
 Russia began airstrikes on ISIS in Syria in late September. 
 
 The film was shot in the ISIS "capital" of Raqqa, Syria. ||||| LONDON (AP) — The latest developments regarding the fight against the Islamic State group in Syria and Iraq: All times local:

 The Islamic State group has released a video in which a Russian-speaking man confesses to spying for Russia's security service and then is shown apparently being beheaded with a knife by another Russian-speaking man. 
 
 The authenticity of the video or the claims in it could not immediately be confirmed and there was no comment from Russia's Foreign Ministry or its FSB security service. 
 
 The man, appearing to be in his late 20s, is shown speaking from a chair. He says he is from Chechnya and was pressured into working for the FSB, to report on Russians who had gone to fight with IS. 
 
 The video then shows the man kneeling on a beach while another man stands behind him, declaring that Russians will be killed in retaliation for Russia's airstrikes in Syria against IS. The man then places a large knife against the prisoner's throat and appears to begin decapitating him.

 Turkish President Recep Tayyip Erdogan has rejected Russian claims that he and his family are profiting from trade in oil with the Islamic State group. 
 
 "No one has the right to make such a slander as to suggest that Turkey buys Daesh's oil," said Erdogan, speaking in Qatar and using an Arabic acronym for the Islamic State group. 
 
 "Turkey has not lost its moral values as to buy oil from a terror organization... Those who make such slanderous claims are obliged to prove them. If they do I would not remain on the presidential seat for one minute. But those who make the claim must also give up their seat if they can't prove it. " 
 
 Russian Deputy Defense Minister Anatoly Antonov and his colleagues on Wednesday showed foreign defense attaches based in Moscow satellite images purporting to show IS transporting oil to Turkey. 
 
 Relations between Turkey and Russia have fallen to a low point since Turkey shot down a Russian jet that it claimed had encroached into Turkish airspace.

 Poland's foreign minister says that the country is mulling how it might support the anti-Islamic State coalition, though it is unlikely that Warsaw would provide troops. 
 
 Foreign Minister Witold Waszczykowski said Wednesday that Poland's Defense Ministry is determining how Poland might help the coalition after U.S. Secretary of State John Kerry appealed for support during a meeting of NATO foreign ministers in Brussels on Tuesday. 
 
 Waszczykowski said: "We will certainly exchange political and intelligence reports. Everything depends on the abilities of the Defense Ministry." 
 
 Poland sent troops to the U.S.-led wars in Iraq and Afghanistan, but many Poles feel bitter that its contributions in Iraq did not bring more benefits to the country.

 British Prime Minister David Cameron says the British government is changing the way it refers to the Islamic State militant group, now calling it Daesh. 
 
 Britain had previously used the acronym ISIL — Islamic State of Iraq and the Levant. Cameron told lawmakers in the House of Commons that he was making the change "because frankly this evil death cult is neither a true representation of Islam nor is it a state." 
 
 Cameron spoke amid an all-day debate about whether Britain should extend airstrikes against IS from Iraq into Syria. 
 
 Daesh is an Arabic acronym for the group's name that also carries negative associations. The Twitter account U.K. Against ISIL — now rebranded U.K. Against Daesh — said the term is hated by the militants because it sound similar to Arabic words meaning "trample" and "one who sows discord."

 The U.S.-led coalition has been pounding Islamic State group targets near the militant-held Iraqi city of Ramadi. Iraqi forces have encircled Ramadi and this week asked the city's civilian residents to leave — a sign that a major operation could be imminent. 
 
 The coalition says its aircraft conducted 15 airstrikes in Iraq on Wednesday, nine of them on IS targets near Ramadi, including fighting positions, vehicles, weapons and buildings. Also hit were IS group units and vehicles in Iraq's north, outside the recently liberated town of Sinjar. 
 
 In Baghdad, coalition spokesman Col. Steve Warren says the strikes are in support of Iraqi operations to liberate Ramadi. 
 
 He says that "with the support of coalition air power, Iraqi forces recently seized the Palestine bridge, which completed the isolation of the city."

 The top NATO commander in Europe, U.S. Air Force Gen. Philip Breedlove, says the bulk of Russia's air operations in Syria are still directed against moderate opposition forces that oppose President Bashar Assad. 
 
 He said there's been some shift in Russian tactics lately but the "vast majority of their sorties" are targeting moderate groups, not Islamic State extremists. 
 
 Breedlove said Wednesday that coalition forces "are not working with or cooperating with Russia in Syria" but have devised safety rules with Russia. 
 
 He says "we have established a safety regime — a series of tactics, techniques and procedures — by which the two groups, the coalition forces and the Russian forces, communicate and try to maintain safety." 
 
 He says the coalition "is focused almost entirely" on fighting Islamic State extremists.

 France's finance minister is calling for tougher rules on imports of art works as part of efforts to dry up financing for the Islamic State group. 
 
 Minister Michel Sapin says Wednesday "we perhaps don't speak enough of financing ... by the sale of works of art" of the group. He said that trafficking of art looted by IS isn't as big a source of money for the extremists as oil, but it is "one element." He says ultimately it is "people in our developed countries" who buy the looted art, sometimes without knowing. 
 
 He said many countries control exports of art works, but there needs to be harmonized rules in Europe and beyond on imports too. 
 
 German counterpart Wolfgang Schaeuble said money-laundering rules should also be expanded to cover art.

 Russia's deputy defense minister says the Turkish president and his family are benefiting from illegal oil trade with Islamic State militants. 
 
 Minister Anatoly Antonov told reporters on Wednesday that Moscow has evidence showing that Turkish President Recep Tayyip Erdogan and his family are involved in the oil trade with IS and personally benefit from it. 
 
 Antonov and his colleagues at the defense ministry's headquarters showed foreign defense attaches based in Moscow some satellite images purporting to show IS transporting oil to Turkey. 
 
 Erdogan has said he would resign if the accusations against him are proven.

 Prime Minister David Cameron has opened a critical debate on whether Britain will take part in airstrikes in Syria, insisting that Britain could make a real difference in the fight against Islamic State militants. 
 
 But Cameron struggled to get through his opening remarks Wednesday as outraged opposition Labour Party lawmakers demanded he retract remarks at a closed-door meeting Tuesday in which Cameron branded opponents of the measure a "bunch of terrorist sympathizers." 
 
 Lawmakers demanded an apology as the 10½ hour debate got underway, arguing the comment showed a lack of respect to those who disagreed with his policy. 
 
 Foreign Secretary Philip Hammond defended Cameron before the debate started, saying the comments weren't aimed at long-time opponents of war such as Labour leader Jeremy Corbyn. Hammond says Corbyn's views were "obviously sincerely held."

 Secretary of State John Kerry has lauded British Prime Minister David Cameron's decision to go to parliament and seek approval for British strikes against IS in Syria. 
 
 Speaking at NATO headquarters, Kerry says "this is a very important step. We applaud his leadership." The US envoy urged the British parliament to approve the request. 
 
 The British vote would authorize the Royal Air Force to launch air strikes against suspected IS positions inside Syria, allowing it to take a more active role in the U.S.-led coalition seeking to weaken the militants held responsible for attacks in Paris, Beirut, Egypt and elsewhere.

 Authorities in Russia's predominantly Muslim republic of Chechnya have organized classes to stave off Islamic State recruitment. 
 
 Thousands of Russian Muslim have joined IS in Syria, and some have taken senior positions. Local students in Chechnya say many of their peers are tempted to go to Syria because they believe in a true Islamic state there. 
 
 Islamic militancy has engulfed Russia's North Caucasus region, the republic of Dagestan in particular, following two separatist wars in neighboring Chechnya. While nearly 1,000 people are believed to have left Dagestan for Syria, the number of Chechen recruits is far lower. 
 
 Chechnya's authoritarian leader Ramzan Kadyrov said last month that less than 500 Chechens are believed to have joined IS and about 200 of them have been killed. Kadyrov has even offered to send thousands of Chechen fighters to fight IS.

 The European Union is trying to close legal loopholes that allow people to travel to Syria or Iraq as foreign fighters and then launch attacks like those in Paris last month when they return home. 
 
 Around 5,000 so-called foreign fighters are thought to be in the EU or come from it, but only about 1,500 are listed on Europe's criminal databases. The EU's executive Commission unveiled proposals on Wednesday that would criminalize attempts to recruit or train people for extremist activities. 
 
 New measures would target those who travel within the 28-nation EU or abroad to work with extremists like the Islamic State group. Others would attempt to choke off access to funds and assets. 
 
 The proposals must still be debated and adopted by EU member countries and the European Parliament.

 Belgian police have raided five more houses in the Brussels area early Wednesday and detained two people for questioning regarding the Paris attacks that left 130 people dead last month. 
 
 The raids targeted people who could have a link to Mohamed Abrini, who was seen driving with Paris fugitive Salah Abdeslam two days ahead of the Nov. 13 Paris attacks, and Ahmed Dahmani, who is detained in Turkey. 
 
 None of Wednesday's detainees have been charged.
– ISIS released a video Wednesday it claims shows a Russian jihadist beheading a Russian spy, NBC News reports. In the video—titled "You Shall be Disappointed and Humiliated O Russians"—the victim identifies himself as Magomed Khasiyev from the Chechen Republic. According to Arutz Sheva, the 23-year-old admits in the video to spying on ISIS to give the Russian government information on the more than 600 Russian citizens who have joined the terrorist organization. In the video, Khasiyev claims he was pressured into working for the Russian Foreign Ministry's security service, the AP reports. The beheading appears to be in retaliation for Russia's bombing campaign in Syria. NBC reports the executioner says in the video—while speaking Russian—that airstrikes "have done nothing but kill peaceful Muslims." He goes on to threaten both Putin and Russian citizens with further attacks, according to Arutz Sheva. "You will not find peace in your homes," CNN quotes the executioner in the video. "We will kill your sons … for each son you killed here. And we will destroy your homes for each home you destroyed here." The video has not been authenticated, nor has there been any confirmation the victim was actually a spy.
