A deadly car bomb attack near northern Syria’s Manbij has suspended negotiations between the Damascus interim government and the Syrian Democratic Forces (SDF), two sources familiar with the issue told Middle East Eye. The attack on Monday killed at least 20 people, most of them women working in agricultural fields.

DAMASCUS (Reuters) -A car bomb killed at least 20 people in the northern Syrian city of Manbij on Monday, the Syrian presidency said, marking the second attack there in three days and the country's deadliest since Bashar al-Assad was toppled from power in December.

The blast, which detonated next to a truck carrying agricultural workers, underscored the challenges faced by the country’s interim president.
