BEIRUT (AFP) - A car bombing killed six people including two children in a Kurdish area of Syria's northern province of Aleppo on Sunday, a monitoring group said.
The Syrian Observatory for Human Rights said the attack targeted a checkpoint in a town controlled manned by Kurdish forces in the Qitna area.
Four Kurdish fighters at the checkpoint were killed, as were two children, it said. More children were among 10 people wounded.
Kurdish fighters in the area are battling militants from the Islamic State in Iraq and Syria (ISIS) extremist group.
The war in Syria began in March 2011 with peaceful protests against President Bashar al-Assad's government, but quickly escalated into an armed rebellion after a brutal regime crackdown.
According to the Britain-based Observatory, which relies on a broad network of activists and medics for its information, more than 200,000 people have been killed in the conflict.
