The U.S. embassy in Iraq says a rocket attack on Baghdad's heavily fortified Green Zone has killed three people and wounded 15 others.
The embassy said those killed in the attack Thursday include two Ugandans and a Peruvian. All of the victims were working for an American security contractor.
The Green Zone is home to Iraqi government buildings as well as the U.S. embassy.
Elsewhere in Iraq Thursday, gunmen killed at least two people in separate attacks, including a Sunni cleric.
Police say the cleric (Fathi al-Nuaimi) was killed in the northern city of Mosul.
In another attack in the city, gunmen killed a bystander after opening fire on a policeman. Police say the officer and another civilian were wounded in the attack.
Mosul has remained an active area for insurgents, even as security in other parts of the country has improved and violence has diminished.
