Police were searching the area after receiving information about two bomb threats. According to police and an interior ministry source, at least 12 people were also wounded.
Earlier on Sunday, a suicide bomber killed five people in Kadhimiya neighbourhood, home to one of Shia Islam’s holiest shrines, shortly before dusk and the end of the daily Ramazan fast. Iraqi officials say attacks in Baghdad and a town south of the Iraqi capital have killed and wounded civilians.
However, the Islamic State militant group is often behind assaults on checkpoints and other locations across the capital as it seeks to challenge Iraqi security forces and Iraq’s Shiite-led government amid intensifying battles in northern and western Iraq.
“Two other civilians were killed and seven injured by a second vehicle bomb that went off near a market in northern Baghdad’s Al-Shaab neighborhood”, the source added.
At least six people were killed and 20 wounded in the attack on the square, which was already targeted in February and has been frequently hit over the years.
Since June 10, 2014, Iraq has witnessed a fresh wave of violence after the ISIL terrorist group took control of large swathes of the war-stricken country.
Security forces said on Sunday they had sealed off areas of northern Baghdad and were sweeping for further bombs.
