Four suicide bombs killed at least 71 people in Iraq today, the latest attacks in an escalating campaign of guerrilla violence that has killed nearly 400 Iraqis since a new government was unveiled two weeks ago.
In Saddam Hussein's hometown of Tikrit, a suicide car bomber blew up his vehicle among a crowd of mainly Shi'ite migrant labourers from southern Iraq who had gathered to look for work.
Police said at least 33 people were killed and 80 wounded.
A policeman at the scene of the blast in Tikrit, 175 km (110 miles) north of Baghdad, said the explosion was near a police station but the target was the crowd of workers.
"What I saw was a tragedy," said Ibrahim Mohammed, a migrant worker from the town of Kut who witnessed the blast. "Some people had their heads torn off by the explosion, some were burned, some were ripped to pieces."
Mainly Sunni guerrillas have often targeted Shi'ites, sparking fears they are trying to stoke sectarian civil war.
