Iraq’s western Anbar province’s police chief Kazim Mohammed al-Fahdawi told Anadolu Agency that in an airstrike against a house in Ramadi’s Zenkune district, the U.S-led coalition killed 11 ISIL militants, including one of its leaders called Suveyd el-Assafi.

Fahdawi said that earlier on Sunday the international coalition had killed at least 40 ISIL militants in several airstrikes in the city of Ramadi, in Anbar. "The U.S.-led coalition destroyed the headquarters of ISIL in Ramadi," he said.

Anbar province in Iraq has the largest displaced population with 83,979 families. It is the area most affected by the current crisis in Iraq, according to the International Organization of Migration.

Separately, at least four people, including two policemen, were killed and 17 others were injured Sunday in capital Bagdad, in bombing and armed attacks by ISIL.

Security sources said that a group of unidentified people attacked the police control point in Al-Zafaraniyah district, in southeastern Bagdad, killing two policemen and injuring four others.

At least two people were killed and 13 others were injured in three different bomb attacks in the Iraqi capital.

Iraq has plunged into a security vacuum since June 2014, when ISIL stormed the northern Iraqi province Mosul and declared what it called a caliphate in Iraq and Syria.

The international coalition led by the U.S. has staged numerous airstrikes against ISIL militants who have taken control of large swathes of territory in Iraq and Syria since mid-June.
