At least five people, four of them students, have been killed in a bombing at a school in Baghdad, the Iraqi capital.
The blast took place on Monday in Baghdad's Shia district of Sadr City, an area that has seen only infrequent attacks because it is encircled by US and Iraqi security forces and has its own neighbourhood security.
A ministry of interior official confirmed the casualties.
The blast also wounded at least 34 people, an Iraqi police official said.
There are an estimated 2.5 million Shia living in Sadr City, a stronghold of Muqtada al-Sadr, known for his anti-US stance.
