Iraqi police say at least seven people are dead and more 15 wounded after insurgents stormed a provincial government compound in Iraq Tuesday.

Witnesses said the attackers blew up two car bombs near the entrance of the compound in Baquba, the capital of Diyala province.

The attack raises concerns about the strength of Iraqi security forces as U.S. troops prepare to withdraw in just a few months.

Reports say shooting could be heard after the gunmen entered the compound.

There are reports the gunmen took hostages, but details are unclear.
