Battles between Turkish-backed groups, supported by air strikes, and Kurdish-led forces killed 37 people yesterday in Syria's northern Manbij region, a war monitor said.
The latest reported fighting comes despite the United States saying Wednesday that it was working to address Turkey's concerns in Syria to dissuade the Nato ally from escalating an offensive against Kurdish fighters.
The Syrian Observatory for Human Rights war monitor reported "fierce battles in the Manbij countryside... in the past hours between the (Kurdish-led) Syrian Democratic Forces and the (Turkish-backed) National Army factions... with Turkish air cover".
"The attacks killed 37 people in a preliminary toll," mostly Turkish-backed combatants, but also six SDF fighters and five civilians, said the British-based Observatory with a network of sources inside Syria.
The monitor said at least 322 people have been killed in fighting in the Manbij countryside since last month.
On Wednesday, Mazloum Abdi, who heads the US-backed SDF, said his group supported "the unity and integrity of Syrian territory". In a written statement to AFP, he called on Syria's new authorities "to intervene in order for there to be a ceasefire throughout Syria".
Abdi's comments followed what he called a "positive" meeting between Kurdish leaders and the Damascus authorities late last month.
Turkish-backed factions in northern Syria resumed their fight with the SDF at the same time as Islamist-led rebels were launching an offensive on November 27 that overthrew Syrian president Bashar al-Assad just 11 days later.
