ALEPPO: Fierce fighting in Syria’s northern city of Aleppo between government forces and Kurdish fighters drove thousands of civilians from ​their homes on Wednesday, with Washington reported to be mediating a de-escalation. The violence, and statements trading blame over who started it, signaled that a stalemate between Damascus and Kurdish authorities that have resisted integrating into the central government was deepening and growing deadlier. Deadly clashes broke out on Tuesday between Syrian government troops and the Kurdish-led Syrian Democratic Forces (SDF).

After relative calm overnight, shelling resumed on Wednesday and intensified in the afternoon, Reuters reporters in the city said.

A spokesperson for Aleppo’s health directorate told Reuters that four civilians had been killed on Tuesday and more than two dozen wounded on Tuesday and Wednesday. Security ‌sources separately told Reuters ‌that two fighters had also been killed.

The health directorate said ‌there ⁠were ​no ‌civilian fatalities on Wednesday, and that it was not authorized to comment on deaths among fighters.

By Wednesday evening, fighting had subsided, the Reuters reporters said. Ilham Ahmed, who heads the foreign affairs department of the Kurdish administration, told Reuters that international mediation efforts were underway to de-escalate. A source familiar with the matter told Reuters the US was mediating.
