Barrages hit Green Zone in Baghdad

By Paul Tait

BAGHDAD (Reuters) - Baghdad's fortified "Green Zone" came under repeated rocket or mortar attack on Sunday, and police said up to 17 people had been killed by rockets falling short outside the government and diplomatic compound.

The attacks were part of a wider increase in violence in the capital and in the northern city of Mosul, underlining warnings by U.S. military commanders that recent security gains in Iraq are both fragile and reversible.

In the past, the U.S. military has blamed such attacks on the Green Zone on rogue elements of Shi'ite cleric Moqtada al- Sadr's Mehdi Army militia. Sadr has imposed a ceasefire on the militia, but there have been signs that it is fraying.

In Mosul, a suicide truck bomber killed 15 Iraqi soldiers and wounded 45 people, including civilians, in an attack on an Iraqi army base, the Interior Ministry said. U.S. commanders describe Mosul as al Qaeda's last urban stronghold in Iraq.

Much of Sunday's violence took place in Baghdad, the centre of sectarian bloodletting between Iraq's majority Shi'ites and minority Sunni Muslims in 2006 and 2007 in which tens of thousands died. A security crackdown by U.S. and Iraqi forces has since sharply reduced levels of violence.

Gunmen in three cars opened fire on pedestrians in the religiously mixed southern district of Zaafariniya, killing at least seven and wounding 16, police said.

Blood and bullet casings littered the street in front of a clinic, market and a housing compound.

"I heard that my brother was killed. I just want to know how the terrorists got through all the checkpoints to reach here," said Zaafaraniya resident Abu Mohammed.
