At least seven people were killed and thirty injured on Saturday in a car blast in a busy market place in the rebel held Syrian town of Azaz near the Turkish border.
Residents and rescuers said the blast occurred during peak late night shopping after the breaking of the fast during the holy month of Ramadan.
"It's timing comes with heavy congestion by shoppers," said Yaseen Shalabi who was near the site of the explosion shopping with his family.
There was no immediate claim of responsibility.
