At least 21 people were injured after a bomb blast tore through a bus in Jerusalem on Monday, Israeli officials said.
The blast was caused by an "explosive device" at the rear of one bus, with fire then spreading to a second bus and a car, officials said.
"Police bomb disposal experts confirm (an) explosive device went off on (the) bus that caused 21 injuries," police spokesman said on Twitter.
The incident happened in Derech Hebron, an area in southwest Jerusalem close to the boundary with the Israeli-occupied West Bank, according to The Associated Press.
