Police spokesman in Diyala province, Maj. Ghalib Al-Karkhi, says a parked car bomb detonated near a military patrol late Monday in Baqouba, killing three soldiers and wounding three others.

Baqouba is a former Al-Qaeda stronghold, 35 miles (60 kilometers) northeast of Baghdad.

Al-Qaeda has frequently targeted Iraqi security forces since the US troops left in December. The group appears to be exploiting a political crisis that has erupted after the Shiite-led government issued an arrest warrant for the Sunni vice president on terrorism charges.
