Syrian authorities warned civilians to leave a contested area in the northern city of Aleppo Thursday and opened a corridor for them to evacuate for a second day as clashes continued between government and Kurdish forces.

The government of Aleppo province gave residents until 1 p.m. local time to evacuate in coordination with the army. State news agency SANA, citing the army, said the military would begin “targeted operations” against the Kurdish-led Syrian Democratic Forces in the neighborhoods of Sheikh Maqsoud, Achrafieh and Bani Zaid half an hour after that deadline.

An Associated Press journalist at the scene heard sporadic sounds of shelling as civilians streamed out of the area Thursday morning. As of Wednesday, more than 46,000 people had been displaced across the province, according to Aleppo’s Directorate of Social Affairs and Labor.

The SDF has said that at least eight civilians were killed in the Kurdish-majority neighborhoods, while government officials reported at least five civilians and one soldier have been killed in the surrounding government-controlled areas in the fighting that broke out Tuesday. Dozens more on both sides have been wounded.

Each side has accused the other of deliberately targeting civilian neighborhoods and infrastructure.

The clashes come amid an impasse in political negotiations between the central state and the SDF.

The leadership in Damascus under interim President Ahmad al-Sharaa signed a deal in March with the SDF, which controls much of the northeast, for it to merge with the Syrian army by the end of 2025. There have been disagreements on how it would happen. In April, scores of SDF fighters left Sheikh Maqsoud and Achrafieh as part of the deal.

Officials from the central government and SDF met again on Sunday in Damascus, but government officials said that no tangible progress had been made.

Some of the factions that make up the new Syrian army, formed after the fall of former President Bashar Assad in a rebel offensive in December 2024, were previously Turkey-backed insurgent groups that have a long history of clashing with Kurdish forces.

The SDF has for years been the main U.S. partner in Syria in fighting against the Islamic State group, but Turkey considers the SDF a terrorist organization because of its association with the Kurdistan Workers’ Party, or PKK, which has waged a long-running insurgency in Turkey. A peace process is now underway.

Despite the long-running U.S. support for the SDF, the Trump administration in the U.S. has also developed close ties with al-Sharaa’s government and has pushed the Kurds to implement the March deal.
