At least 30 people were killed and more than 60 others wounded when a truck went off near a Sunni mosque in the western Iraqi town of Habbaniyah on Saturday, local police said.

The attack took place at about 3:30 p.m. (1230 GMT) near a Sunni mosque in a market in the town of Habbaniyah, 80 km west of Baghdad, the source told Xinhua on condition of anonymity.  

The blast hit dozens of worshippers who were leaving the mosque after prayer services, he said.

Iraqi PM: around 400 insurgents killed in Baghdad crackdown

The U.S. and Iraqi security forces have killed some 400 suspected insurgents and detained a similar number of people during the 11-day-old major security clampdown in the capital, Prime Minister Nuri al-Maliki said on Saturday.

"So far, we have 426 suspected militants who had been detained and around that number have been killed during the crackdown," Maliki told reporters during a visit to command headquarters for the operation dubbed "Operation Imposing Law."

On Feb. 14, Maliki announced the start of a new security plan in Baghdad and other Iraqi cities.

Under the security plan, Baghdad is divided into 10 districts, jointly patrolled by U.S. troops and forces from Iraqi defense and interior ministries.

U.S. President George W. Bush has decided to send 21,500 more American troops to Iraq and thousands of them have arrived in Baghdad to support the security plan.
