The official -- who was not named -- is an "experienced bomb maker and facilitator" and one of IS's top leaders in Syria, the coalition said.

"The mission was meticulously planned to minimize the risk of collateral damage, particularly any potential harm to civilians," it said in a statement.

"There were no civilians harmed during the operation nor any damage to coalition aircraft or assets."

After losing their last territory following a military onslaught backed by the US-led coalition in March 2019, the remnants of IS in Syria mostly retreated into desert hideouts.

They have since used such hideouts to ambush Kurdish-led forces and Syrian government troops while continuing to mount attacks in Iraq.

The militant group's former leader, Abu Ibrahim al-Qurashi, was killed in early February when he detonated a bomb to avoid capture during a US raid in northwest Syria, the White House and US defence officials said.

The group has vowed to avenge the killing, with a spokesman recently calling on supporters to resume attacks in Europe, taking advantage of the "available opportunity" of "the crusaders fighting each other" -- referring to Russia's invasion of Ukraine.

His demise was the biggest setback to IS since his predecessor, the better-known Abu Bakr al-Baghdadi, was killed about 15 kilometres (nine miles) away during a US commando raid in 2019.

Little is known about new leader Abu Hasan al-Hashemi al-Qurashi, the jihadist group's third chief since its inception.
