A suicide bomber attacked a security checkpoint in northern Baghdad Sunday, killing at least 14 people, Iraqi officials said.

The bomber, who was on foot, detonated his device at one of the busy entrances of the Shiite district of Kadhimiyah, killing at least 10 civilians and four policemen, a police officer said. At least 31 other people were wounded, he added.

Three more civilians were killed and 11 wounded in a bomb explosion in an outdoor market in Baghdad’s western suburb of Abu Ghraib, another police officer said. Two medical officials confirmed the casualty figures.

In an online statement, Daesh (ISIS) claimed responsibility for the Kadhimiyah attack, saying it targeted a gathering of security forces and Shiite militia members. Security forces and public areas, mainly in Shiite neighborhoods, are one of the most frequent targets for Daesh, which controls key areas in mainly northern and western Iraq.
