At least 7 people were left dead and 20 wounded in an eight-hour stand-off in Iraq's capital city of Baghdad as Iraqi special forces stormed a Catholic Church where the gunmen held about 50 people as hostages.
Martin Chulov, a journalist for the U.K.-based Guardian newpaper who was in the scene said that one of the gunmen entered the room and threw an unidentified explosive device inside, causing some casualties.
Before the incident, the gunmen attacked the now famed Baghdad Stock Market, in the central part of the Iraqi capital, earlier Sunday killing two guards and wounding 4 others and detonated two car bombs outside the stock exchange.
The hostage takers demand the release of detainees and prisoners inside the Iraqi prisons in exhange for the hostages but the authorities warned them that they will storm the Sayidat al-Nejat church if they don't release the hostages and surrender themselves after sealing the area and evacuating the civilians.
After a few hours, a firefight erupted and explosions are heard. The US forces the other hand provided UAV (unmanned aerial vehicle) support with video imagery of the incident.
