BAGHDAD, Nov. 13 (Xinhua) -- A civilian was killed and 16 people were wounded on Sunday in attacks by three car bombs and a roadside bomb in the Iraqi capital of Baghdad, a police source said.
A booby-trapped car detonated in the district of Sadr City in eastern Baghdad, leaving a civilian killed and five others wounded, the source told Xinhua on condition of anonymity.
Another car bomb went off near a mosque in the Shiite district of Obiedi in the eastern part of Baghdad, wounding six people, the source said.
A third car bomb was discovered in Shaab district in northeastern Baghdad, and was defused by explosive experts without casualty, the source added.
In addition, a roadside bomb detonated near a Shiite mourning tent in al-Ghadier district in southeastern Baghdad, wounding five people, the source said.
The tent was set up for Shiite Muslims to commemorate the death of Imam Hussein, one of the Shiites' twelve most revered Imams, who was killed in 680 A.D. and buried in Karbala, some 110 km south of Baghdad.
The Shiite Muslims had already observed the death day of Imam Hussein on Oct. 12, in a ritual named Ashura Day, but they usually continue their mourning till the ritual of al-Arbaeen, or 40 days after the Imam's death which will take place on Nov. 21.
No group has so far claimed responsibility for the attacks, but the Islamic State (IS) militant group, in most cases, is responsible for deadly attacks against Shiite Muslims and crowded areas, including markets, cafes and mosques across Iraq.
Terrorist acts, violence and armed conflicts killed 1,792 Iraqis and wounded 1,358 others in October across Iraq, the United Nations Assistance Mission for Iraq said.
Many blame the current chronic instability, cycle of violence, and the emergence of extremist groups, such as the IS, on the U.S., which invaded and occupied Iraq in March 2003.
