The Syrian government has accused Kurdish leaders of “treason” for organising a conference with allied Arab tribes to plot out the political future of territory under their alliance’s control.
Kurdish police spokesman Ali Al Hassan said the car bomb was detonated by "remote control" near a school, "killing a member of our (police) forces".
US forces in Syria started pulling back on Monday from Turkish border areas, opening the way for Ankara’s threatened military invasion and heightening fears of a extremist resurgence.
Ankara stepped up its assault on Kurdish-held border towns in northeastern Syria on Saturday, defying mounting threats of international sanctions, even from Washington.
The reality is, that such moments are taking place as I pen this article and as you are reading it, injustices committed by people on a massive scale are not confined to history books, they are happening right now. Meanwhile, we have become the people who the next generation will ask themselves about: how did we allow such events to happen?
Battles raged on Friday as Turkish President Recep Tayyip Erdogan vowed to press an assault against Kurdish forces in Syria, dismissing "threats" from other countries while the US warned Ankara of fresh sanctions.
The president previously said that Turkey's patience was wearing thin after Turkish and American officials agreed in August to establish a buffer zone in northern Syria.
Ankara and Washington agreed on Thursday to a five-day truce in northeastern Syria to allow the Syrian Kurdish YPG militia to withdraw from a "safe zone" that Turkey aims to establish. Erdogan has said the offensive will resume if the withdrawal is not complete within the five days.
The ministry said in a statement that the attack violated Ankara's agreements and cooperation with Russia, Syrian President Bashar Al Assad's most powerful ally. It said Russia had been told in advance about the convoy.
