Two women and a child from the same family were killed and five other people were wounded in an attack Saturday in Syria's northern city of Minbej, authorities said.
A "terrorist explosion" occurred as a vehicle carrying civilians passed the entrance to Minbej, an Arab-majority city under Kurdish administration, the Minbej military council said without providing further details.
The Britain-based Syrian Observatory for Human Rights war monitor said the blast was a car bomb.
AFP quoted it as saying that two civilians were killed and five wounded, including two members of the Kurdish Asayesh security forces.
The Kurdish-led Syrian Democratic Forces, the regional administration's main fighting force, spearheaded the fight against ISIS.
It controls vast areas of territory in war-torn Syria's east and northeast.
