“U.S. planes bombed a house in the Aziziyah area of Ramadi city centre, killing 13 civilians," Ali al-Obeidi, a doctor at Ramadi hospital said.
He added that the U.S. assault also wounded four people.
The U.S. army confirmed that its forces carried out a military operation in Ramadi, but refused to provide further information.
