(Reuters) - A dozen car bombs and suicide blasts tore into Shi'ite districts in Baghdad and south of the Iraqi capital on Tuesday, killing more than 50 people on the 10th anniversary of the U.S.-led invasion that ousted Saddam Hussein.
Sunni Islamist insurgents linked to al Qaeda have vowed to step up attacks on Shi'ite targets since the start of the year in an attempt to provoke sectarian confrontation and undermine Shi'ite Prime Minister Nuri al-Maliki's government.
Tuesday's bombs exploded in a busy Baghdad market, near the heavily fortified Green Zone and in other districts across the capital. A suicide bomber also attacked a police base in a Shi'ite town south of the capital, officials said.
"I was driving my taxi and suddenly I felt my car rocked. Smoke was all around. I saw two bodies on the ground. People were running and shouting everywhere," said Ali Radi, a taxi driver caught in one of the blasts in Baghdad's Sadr City.
A decade after U.S. and Western troops swept Saddam from power, Iraq still struggles with insurgents, sectarian friction and political feuds among Shi'ite, Sunni and Kurdish factions.
In a sign of concern over security, the cabinet on Tuesday postponed local elections in two provinces, Anbar and Nineveh, for up to six months because of threats to electoral workers and violence there, according to Maliki's media adviser Ali al-Moussawi. The polls will go ahead elsewhere on April 20.
58% of Americans say the war in Iraq was not worth fighting.
Who exactly are the 42% who either think the war was worth fighting or aren't sure about it?
Ten years after the war, we've left the place a slaughter ground.
And it all it cost was a couple of trillion bucks.
That really is a heckuva job.
