Turkey shells US-backed Kurdish forces positions in Syria - media reports
The Turkish army on Sunday fired artillery shells at positions held by U.S.-backed Kurdish fighters in northern Syria, Stars and Stripes website reported.
The shelling targeted People's Protection Units (YPG) positions east of the River Euphrates in northern Syria, it said.
Turkey considers the YPG a terrorist organisation and an extension of its own insurgent group the Kurdistan Workers' Party, which took up arms in 1984 against the Turkish state. The YPG forms the backbone of the U.S.-backed Syrian Democratic Forces in the battle against Islamic State.
According to Turkish state-run Anadolu news agency, Turkish armed forces bombarded barricades and positions "erected by the terrorist organisation" in the Zor Magar region in Kobane.
The shelling came after Turkey hosted a summit on the peace process for Syria. The leaders of Russia, Germany, France and Turkey stressed the importance on Saturday of a lasting ceasefire in Syria and said a committee to write a new constitution should meet by the end of the year.
Turkish President Recep Tayyip Erdoğan has repeatedly threatened to launch a new offensive in the east of the Euphrates, and on Friday said he was giving the YPG a final warning.
