DAMASCUS - The Kurdish-led Syrian Democratic Forces (SDF) launched rocket and artillery attacks in northern Syria, injuring at least seven people, including four Syrian soldiers and three civilians, Syrian Arab News Agency (SANA) reported, citing the Syrian Ministry of Defense.

The attacks targeted a village near Manbij in the northern Aleppo province, using multiple rocket launchers and artillery shells "irresponsibly and for unknown reasons," said the ministry.

A barrage of rockets and artillery shells reportedly damaged civilian homes and prompted a swift military response from Syrian army units in the area, it said.

The defense ministry said that the Syrian forces repelled an infiltration attempt by SDF fighters near one of its military posts west of Manbij.

In response, the Syrian forces launched "precise strikes" against SDF artillery positions, including a rocket launcher and field cannon detected in eastern Aleppo.

The flare-up comes despite recent coordination efforts between Damascus and Kurdish authorities aimed at presenting a unified stance on national and security issues.

The reasons behind the sudden escalation remain unclear.

In March, the Syrian interim government and the SDF reached a deal on merging all civil and military institutions in the Kurdish-controlled region under state institutions, according to SANA, the Syrian state news agency.
