16 Killed in Attacks in Baghdad and Tikrit

Violence in Baghdad and central Iraq on Monday killed 16 people, including 12 struck by a car bomb driven by a suicide attacker in Saddam Hussein's home town of Tikrit, officials said.

The unrest came three days after attacks at a Tikrit mosque and hospital where victims were being treated killed 24, raising doubts over the capabilities of Iraqi security forces just months before all U.S. forces must pull out.

Monday's attack killed 12 people, including military intelligence Colonel Nuri Sabah al-Mashhadani and two other officers, and wounded 20 others, according to a police captain and an army captain, both of whom spoke on condition of anonymity.

Nine soldiers were among the dead, including the three officers.

Salaheddin provincial health director Raid al-Juburi had earlier put the toll at eight dead and 17 wounded.

The explosion struck at 9:30 am (0630 GMT), targeting the main gate of a fortified compound housing several of Saddam's presidential palaces, which is home to security offices and also the mosque that was attacked on Friday.

The compound is locally called Tikrit's "Green Zone," referring to the heavily secured center of Baghdad where parliament and the U.S. embassy are located.

Friday's violence was the worst in Tikrit since a March 29 al-Qaida raid on the city's provincial council offices, which led to an hours-long firefight with security forces that killed 58 people.

Tikrit is the capital of mainly Sunni Arab Salaheddin province, which was a key battleground in the insurgency that followed the U.S.-led invasion of 2003.

In Baghdad, two attacks by gunmen on checkpoints in the mainly Sunni northern neighborhood of Adhamiyah killed three, one soldier and two anti-Qaida militiamen, and wounded two others, an interior ministry official and a military official said.

And a car bomb in the eastern district of Palestine Street killed one person and wounded 10 others, the ministry official said.

The latest violence raise questions over the ability of Iraqi forces to secure the country, with 45,000 American troops due to withdraw at the end of the year under the terms of a bilateral security pact.

Iraqi leaders are still considering whether to request an extension of the U.S. military presence, and top American officials have pressed their Iraqi counterparts to decide soon.

U.S. forces in Iraq are charged primarily with training and equipping local forces, but they still take part in joint counter-terror operations.

Violence in Iraq is down from its peak in 2006 and 2007, but attacks remain common. A total of 177 people died in May as a result of violence, according to official figures.
