"We support the efforts of other countries, including members of the US-led international coalition, in the anti-terrorist direction," Moscow's foreign ministry said in a statement, while also calling for a "thorough investigation" should civilian casualties of the US raid be confirmed.

US President Joe Biden said on Thursday that the leader of Islamic State Abu Ibrahim al-Hashemi al-Quraishi died when he blew himself and family members up during a US military raid in Syria.

Quraishi had led Islamic State since the death in 2019 of its founder Abu Bakr al-Baghdadi, who was also killed when he detonated explosives during a raid by US commandos.
