BAGHDAD • Four bombings killed dozens of people and wounded more than 100 in Baghdad yesterday, police and medical sources said, extending the deadliest spate of attacks in the Iraqi capital so far this year.

A suicide bombing claimed by the Islamic State in Iraq and Syria (ISIS) in a marketplace in the northern, mainly Shi'ite Muslim district of Shaab killed 38 people and wounded more than 70, according to Reuters.

Shortly afterwards, a bomb struck a fruit-and-vegetable market in southern Baghdad's Rashid district, killing at least five people, BBC reported.

This was followed by a car bomb in nearby Shi'ite Sadr City which left at least 19 more dead and 17 wounded, Reuters reported. BBC said a separate bomb attack in a restaurant killed nine others.

There were no immediate claims of responsibility for the last three bombings.

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

But attacks claimed by ISIS 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.
