A senior member of the so-called Islamic State has been killed in an airstrike in the Iraqi city of Mosul, according to Reuters news agency.

Radwan Taleb al-Hamdouni was thought to be the militant group's leader in the northern Iraqi city, which the jihadists overran in June.

He was killed along with his driver in the western part of the city on Wednesday afternoon and buried the same day, Reuters said, citing residents and a medical official.

The US-led coalition has launched a series of airstrikes in Iraq and Syria in recent weeks, targeting militant strongholds and the leadership.

Washington has said its aerial campaign is aiming to degrade the militants' capability in the region. Another senior Islamic State member, Abdul Rahman al-Athaee, who was a senior aide to the leader Abu Bakr al-Baghdadi, was killed in a US air strike on November 9.

Meanwhile, the jihadist group suffered a further setback in Iraq this week, after Iraqi security forces re-took the Baiji oil refinery following months of fighting in the surrounding areas.
