(Updates death toll)
BEIRUT, May 15 (Reuters) - At least 29 people were killed when a car bomb went off at a Syrian border post on the frontier with Turkey on Thursday, the Syrian Observatory for Human Rights said.
It said the dead included five women and three children.
Pictures sent by activists showed burnt cars and charred corpses and body parts in the area. They said scores of people were wounded in the explosion.
"At least 12 ambulances have transported wounded people into Turkey, the death toll is very high," one activist in the area said.
