Turkey has launched airstrikes against alleged targets of the Kurdistan Workers' Party (PKK) in northern Iraq, where the armed group has bases, the state-run Anadolu news agency reports.
Turkey's war against Kurdish militants is taking place on three fronts: inside its own borders, in northern Syria and in northern Iraq.
Broadcaster CNN Turk quoted the Turkish military as saying it had struck 20 targets 61 times in Syria in the past 24 hours.
Syrian rebels backed by the Turkish army took control of 11 villages from Kurdish-led forces in the north of the country in the past two days, while capturing only two new villages from Islamic State extremists, the Syrian Observatory for Human Rights reported Monday.
Syrian rebels backed by Turkish tanks and jets pushed deeper into territory held by Kurdish-led forces in northern Syria on Sunday, leaving some 35 civilians dead in two separate attacks, a monitoring group said.
