Baghdad - Two Iraqi soldiers were killed and four civilians were wounded in a blast in the northern city of Mosul, police said.

The bomb went off in the al-Akhaa district of eastern Mosul, police told the German Press Agency dpa.

It was the second blast in Mosul on Tuesday. Earlier, seven people were killed and 25 were injured when a man drove a truck laden with explosives toward a police station in al-Mahata district, south of Mosul.

Iraqi security forces have arrested more than 100 insurgents in Mosul, some 400 kilometres north of Baghdad, since they began an offensive dubbed "Operation New Hope" on February 20.

Insurgents have responded with near-daily attacks in and near the city, which remains among Iraq's most dangerous. (dpa)
