Turkish raids in northern Syria on Sunday struck outposts operated by the Syrian army and Kurdish-led forces, killing three, a Britain-based war monitor said. The raids near the Kurdish-held border town of Kobane targeted positions of the Syrian army and the Syrian Democratic Forces, the Syrian Observatory for Human Rights said. The three casualties were wearing Syrian army uniform, according to the monitor. Several other fighters were wounded, some in critical condition, according to the Observatory, which relies on a wide network of sources inside Syria. The strikes were preceded by cross-border shelling from near Kobane against Turkish forces, according to the monitor. Last month, the Syrian government said it would respond to direct attacks by Turkey against its forces. The warning came after a Turkish raid on a regime outpost near Kobane killed at least three troops in mid-August, according to the official SANA news agency. Turkey has launched a series of cross-border offensives targeting Kurdish forces and the Islamic State group since 2016, but such operations have rarely resulted in the killing of Syrian regime fighters.
