Ten people were killed and more than 20 wounded in an explosion in east Baghdad on Saturday, according to security and medical sources.

The commander of security forces in Baghdad, Ahmad Salim, said in a statement that the explosion is “an accident and not an act of terrorism.”

Earlier, security sources said that the explosion took place in a garage near a football stadium and a café, when an explosive device attached to a vehicle detonated, leading to another explosion of a gas tanker that was close by.

Most of the victims were amateurs playing football in their neighborhood stadium.

A military statement said a gas tanker exploded in a garage in East Baghdad causing a number of casualties and security forces are investigating the cause of the explosion, without giving further details.

Iraq's recently elected President Abdul Latif Rashid promised there would be an investigation to identify those responsible for the accident.
