identity. The body was recovered by the US military and was in its custody until, according to one US official, his body was buried at sea according to Islamic traditions. One US official said that "finding a country willing to accept the remains of the world's most wanted terrorist would have been difficult." US State Department issued a "Worldwide caution" for Americans following bin Laden's death and US diplomatic facilities everywhere were placed on high alert, a senior US official said. Crowds gathered outside the White House and in New York City's Times Square to celebrate bin Laden's death. Syria In 2003, President Bashar al-Assad revealed in an interview with a Kuwaiti newspaper that he doubted Al-Qaeda even existed. He was quoted as saying, "Is there really an entity called Al-Qaeda? Was it in Afghanistan? Does it exist now?" He went on further to remark about bin Laden, commenting "[he] cannot talk on the phone or use the Internet, but he can direct communications to the four corners of the world? This is illogical."

On February 2, 2014, Al-Qaeda distanced itself from ISIS and its actions in Syria; however, during 2014–15, ISIS and the Al-Qaeda-linked al-Nusra Front were still able to occasionally cooperate in their fight against the Syrian government. Al-Nusra (backed by Saudi Arabia and Turkey as part of the Army of Conquest during 2015–2017) launched many attacks and bombings, mostly against targets affiliated with or supportive of the Syrian government. From October 2015, Russian air strikes targeted positions held by al-Nusra Front, as well as other Islamist and non-Islamist rebels, while the US also targeted al-Nusra with airstrikes. In early 2016, a
