 WASHINGTON (AP) — The United States, France and Britain together launched military strikes in Syria to punish President Bashar Assad for a suspected chemical attack against civilians and to deter him from doing it again, President Donald Trump announced Friday. Explosions lit up the skies over Damascus, the Syrian capital, as Trump announced the airstrikes from the White House. 
 
 Syrian television reported that Syrian air defenses have responded to the attack. 
 
 Trump said the U.S. is prepared to "sustain" pressure on Assad until he ends what the president called a criminal pattern of killing his own people with internationally banned chemical weapons. It was not immediately clear whether Trump meant the allied military operation would extend beyond an initial nighttime round of missile strikes. 
 
 Trump did not provide details on the joint U.S.-British-French attack, but it was expected to include barrages of cruise missiles launched from outside Syrian airspace. He described the main aim as establishing "a strong deterrent" against chemical weapons use. The Syrian government has repeatedly denied any use of banned weapons. 
 
 The decision to strike, after days of deliberations, marked Trump's second order to attack Syria; he authorized a barrage of Tomahawk cruise missiles to hit a single Syrian airfield in April 2017 in retaliation for Assad's use of sarin gas against civilians. 
 
 Trump chastised Syria's two main allies, Russia and Iran, for their roles in supporting "murderous dictators," and noted that Russian President Vladimir Putin had guaranteed a 2013 international agreement for Assad to get rid of all of his chemical weapons. He called on Moscow to change course and join the West in seeking a more responsible regime in Damascus. 
 
 The allied operation comes a year after the U.S. missile strike that Trump said was meant to deter Assad from further use of chemical weapons. Since that did not work, a more intense attack would aim to degrade his ability to carry out further such attacks, and would try to do this by hitting Syrian aircraft, military depots and chemical facilities, among other things. 
 
 The one-off missile strike in April 2017 targeted the airfield from which the Syrian aircraft had launched their gas attack. But the damage was limited, and a defiant Assad returned to episodic use of chlorine and perhaps other chemicals. 
 
 A broader question is whether the allied attacks are part of a revamped, coherent political strategy to end the war on terms that do not leave Assad in power. ||||| White House press secretary Sarah Huckabee Sanders speaks during the daily briefing at the White House in Washington, Friday, April 13, 2018.

 He says there is "no doubt" that the Syrian government is responsible. President Bashar Assad's government denies responsibility.

 President Donald Trump is reiterating his call to have other nations take on more of the burden in Syria. 
 
 Trump says he has asked U.S. partners "to take greater responsibility for securing their home region, including contributing large amounts of money for the resources, equipment and all of the anti-ISIS effort." 
 
 He says increased engagement from countries including Saudi Arabia, the United Arab Emirates, Qatar and Egypt can ensure that Iran does not profit from the defeat of the Islamic State group. 
 
 He adds that, "America does not seek an indefinite presence in Syria — under no circumstances" and says that, "As other nations step up our contributions, we look forward to the day when we can bring our warriors home."

 President Donald Trump is warning Russia and Iran about their association with Syrian strongman Bashar al-Assad's government, as he announces the launch of retaliatory strikes after an apparent chemical weapons attack last week. 
 
 Speaking from the White House, Trump says, "To Iran and to Russia, I ask: What kind of a nation wants to be associated with the mass murder of innocent men, women and children?" 
 
 Trump calls the two countries those "most responsible for supporting, equipping and financing the criminal Assad regime."

 He adds ominously, "Hopefully someday we'll get along with Russia, and maybe even Iran, but maybe not."

 President Donald Trump says he is "prepared to sustain" strikes against Syria until the use of chemical agents stops. 
 
 The United States, along with assurance from France and the United Kingdom, launched a response Friday against the regime of Syrian leader Bashar al-Assad days after his government allegedly used chemical weapons on its citizens. 
 
 But Trump says America does not seek "an indefinite presence" in Syria and will look to pull out its troops once the Islamic State is totally defeated. 
 
 Trump has signaled in recent weeks that, despite advice from his national security team, he wanted to accelerate the timetable of the withdrawal of American forces.

 President Donald Trump is set to address the nation Friday night amid anticipation of a retaliatory strike for an apparent Syrian chemical weapon attack last week. 
 
 That's according to a source familiar with the president's plans, who was not authorized to speak publicly. 
 
 Trump has said he will hold the Syrian government, as well as its Russian and Iranian allies, accountable for the suspected attack. 
 
 White House spokesman Raj Shah said Friday afternoon that Trump "is going to hold the Syrian government accountable. He's also going to hold the Russians and the Iranians who are propping up this regime responsible."

 The U.S. Navy was moving an additional Tomahawk missile-armed ship within striking range of Syria as President Donald Trump and his national security aides mulled the scope and timing of an expected military assault in retaliation for a suspected poison gas attack. 
 
 Trump's U.N. ambassador, Nikki Haley, said the president had not yet made a final decision, two days after he tweeted that Russia should "get ready" because a missile attack "will be coming" at Moscow's chief Middle East ally. 
 
 The presence of Russian troops and air defenses in Syria were among numerous complications weighing on Trump, who must also consider the dangers to roughly 2,000 American troops in the country if Russia were to retaliate for U.S. strikes.
