BAGHDAD: A suicide bomber blew up his booby-tapped car early Monday outside an Iraqi army battalion headquarters in the country's east, killing 10 soldiers and wounding 29 people in a bombing that brought down the building. Diyala provincial council spokeswoman Samira al-Shibli said emergency workers were still frantically trying to rescue victims from beneath the rubble several hours later. Diyala health directorate spokesman Faris al-Azawi said the bomber drove his car past a security gate and detonated his explosives right outside the headquarters of an army intelligence battalion in Kanan, east of the provincial capital of Baqouba, 60 km northeast of Baghdad. An army commander in Diyala described a horrific scene of the building collapsing on soldiers inside. He said the bomber drove his car up through a back gate and through a yard to get to the headquarters. The commander spoke on condition of anonymity because he was not authorized to brief the media. He said dozens of soldiers were killed or wounded. Al-Azawi said 10 soldiers were killed. He said at least 29 people also were wounded, including 14 soldiers.
