Two explosions in the Iraqi capital, Baghdad, have killed at least 13 people and wounded more than 20 others.
Several cars in the area were burned in the blasts
The bombs exploded in quick succession near a petrol station in the western suburb of Mansour.
There had been a relative lull in major attacks during the Muslim festival of Eid al-Adha which ended this week.
An increase in the number of attacks has also been expected following the execution on Saturday of former Iraqi leader Saddam Hussein.
The blasts in Mansour set fire to the petrol station and burned several cars in the area, reports said.
A member of the Iraqi security services in Mansour told the BBC that both of the explosions were car bombs.
"Somebody detonated two cars against people as they were queuing for petrol," the unnamed man said.
"What do they want from us?" he asked, adding: "They have killed all these people. Some are burnt."
TV footage showed the wounded lying on stretchers in a crowded hallway at Yarmouk hospital in south-west Baghdad.
