At least 15 people have been killed in two explosions in the Iraqi capital of Baghdad, officials said on Monday.

A suicide bomber struck at a security checkpoint in a Shia neighbourhood in the north of the city, killing thirteen civilians during morning rush hour.

The neighbourhood, which houses one of Shia Islam's holiest shrine, has witnessed many similar attacks in the past carried out by militant Sunni groups associated with al-Qaeda.

Two people were killed in a separate blast in another northern suburb.

The attacks are the latest in a wave of bombings that have struck the Iraqi capital, where a decade-long night-time curfew was lifted on Saturday.

The government had wanted to return a sense of normality to the city but 37 people were killed in a series of blasts on Saturday.

No group has yet claimed responsibility for the attacks.
