BAQUBA, Iraq, Sept. 16 (Xinhua) -- Two people were killed in a suicide bomb attack in Iraq's eastern province of Diyala on Saturday, a provincial police source said.
A suicide bomber detonated his explosive belt near a shop in Jihad district in the city of Maqdadiyah, some 100 km northeast of Baghdad, during a heavy shootout, when another bomber opened fire before fleeing to a nearby alley in the district, the source told Xinhua on condition of anonymity.
The attacks left a police officer and a civilian killed, and seven people wounded, three of them in critical condition, the source said.
Meanwhile, five mortar rounds landed in the district without causing casualties, the source added.
The city authorities imposed curfew after the attacks, while security forces launched a search for the second suicide bomber, the source said.
No group has yet claimed responsibility for the attacks, but Islamic State (IS) militants, in most previous cases, carried out such suicide attacks targeting security forces and crowded areas, including markets, cafes and mosques across Iraq.
IS militants still controls the Himreen mountainous area, including its lake, in northern and eastern parts of Diyala.
The group also has a major redoubt in Mteibijah area on the provincial border with Salahudin Province, which extends to the sprawling rugged area from the western part of Salahudin to the desert in the neighboring Anbar Province in western Iraq.
