An attack on a Shia mosque by a suicide bomber in Baghdad killed 13 people Monday, and came soon after a call from unity by Iraq's new prime minister.
The explosion was caused by the detonation of a vest full of explosives during noon prayers in the mosque in the southeastern section of New Baghdad. An unconfirmed number of people were injured. The cities of Karbala and al-Hillah, each south of Baghdad, were the sites of car bomb detonations Monday as well.
It has not been determined if the incidents are connected to the shooting deaths Friday of over 70 people at a Sunni mosque in northeastern Iraq, but they reinforce the challenges Prime Minister Haider al-Abadi faces in unifying the country.
