Three bombings in Baghdad kill 63

Three bombings killed at least 63 people and wounded more than 100 in Baghdad today, police and medical sources said, extending the deadliest spate of attacks in the Iraqi capital so far this year.

A suicide bombing claimed by Islamic State in a marketplace in the northern, mainly Shi'ite Muslim district of al-Shaab killed 38 people and wounded over 70, while a car bomb in nearby Shi'ite Sadr City left at least 19 more dead and 17 wounded.

Another car bomb, in the mixed Shi'ite-Sunni southern neighbourhood of al-Rasheed, killed six and wounded 21, the sources said, in what a military spokesman described as a suicide attack.

Security has improved somewhat in Baghdad in recent years, even as the Sunni militant Islamic State (IS) seized swathes of the country almost up to the outskirts of the capital.

But attacks claimed by IS in and around the city last week killed more than 100 people, sparking anger in the streets over the government's failure to ensure security.

There are fears that Baghdad could relapse into the bloodletting of a decade ago when sectarian-motivated suicide bombings killed scores of people every week.

That has cranked up pressure on Prime Minister Haider al-Abadi to resolve a political crisis or risk losing control of parts of Baghdad even as the military wages a counter-offensive against Islamic State in Iraq's north and west with the help of a US-led coalition.

Abadi has said the crisis, sparked by his attempt to reshuffle the cabinet in an anti-corruption bid, is hampering the fight against Islamic State and creating space for more insurgent attacks on the civilian population.

A spokesman for the Baghdad Operations Command told state television the attacker in the al-Shaab neighbourhood had detonated an explosives-filled vest in coordination with a planted bomb. Initial investigations revealed that the bomber was a woman, he said.

Islamic State said in a statement distributed online by supporters that one of its fighters had targeted Shi'ite militiamen with hand grenades and a suicide vest. There were no immediate claims of responsibility for the other two bombings.
