According to BBC News
The US Special Forces have launched an operation in the northern Syrian province of Idlib, near the Turkish border.
US President Joe Biden has announced that Abu Ibrahim Hashemi Qureshi, the leader of the Islamic State (ISIS) group, has been killed in the operation.
Initial reports from Atma village indicated that at least 12 people had been killed in the attack, several of them civilians.
The London-based Syrian Observatory for Human Rights put the death toll at seven.
This is the largest such US operation since the assassination of Abu Bakr al-Baghdadi, the former leader of ISIS.
The attack took place in the last Syrian province, which is still a militant base opposed to Bashar al-Assad and is dominated by extremist Islamist groups.
According to the New York Times, one of the American helicopters used to transport the commandos to the operation site was damaged during the attack and was destroyed by an American fighter.
Joe Biden has said that all US troops involved in the operation have returned to safety.
Various news sources and eyewitnesses say that the US commando operation was a relatively large ground attack and led to an unexpected clash that lasted several hours.
The scale of the attack has led the American media to speculate about the possibility of targeting an al-Qaeda leader.
The Pentagon had postponed the announcement of the target to a DNA test.
The United States has used drone strikes to target al-Qaeda in northern Syria. The number of civilians killed in drone strikes has drawn much criticism from the US government.
