Officials in Iraq say two bomb attacks in the country have killed at least seven people and wounded about 20 others.

In the deadliest attack Sunday, a bomb exploded in a market in the eastern town of Khalis in Diyala province, killing four people. Officials say the bomb targeted the town's mayor, whose condition was unclear.

Diyala province still sees frequent insurgent attacks despite significant drops in violence elsewhere in Iraq.

In the other incident, a female suicide bomber blew herself up at a hospital near the western town of Fallujah in Anbar province, killing three people.

Anbar is a former stronghold of al-Qaida insurgents. U.S. forces handed over security control of the province to Iraqi forces two months ago.
