One Turkish soldier was killed and three others wounded Tuesday in Turkey's southeastern Diyarbakir province in new violence blamed on the outlawed Kurdistan Workers' Party (PKK), the army said.

Fighting erupted during an operation to "capture and neutralise" the militants after they had blocked a road connecting the Lice district of Diyarbakir to Bingol province in southeast Turkey, the army said in a statement. 

A pro-Islamic State jihadist video has urged Turks to rise up against President Recep Tayyip Erdogan, accusing him of being a traitor who has sided with the United States and Kurdish militants.

The video -- said to have been recorded in the IS-controlled Raqa province of northern Syria -- is one of the clearest such threats yet made by the Islamic State extremists against Turkey.

Five Syrian migrants died early Tuesday when a boat taking them from Turkey to Greece capsized, reports said, with a survivor telling Agence France Presse the victims were trapped in the hull.

Turkey's official Anatolia news agency reported that 24 migrants had been rescued after the fibreglass boat overturned after leaving Turkey's Bodrum peninsula for the Greek Aegean island of Kos. The corpses of five migrants from the boat were found, it added.

Duaa, a 22-year-old Syrian refugee and mother of two, is nervously counting down the hours in the Turkish resort city of Bodrum, hoping this will be the night her family's life will finally take a turn for the better.

She says her husband paid people-smugglers $1,200 (1,000 euros) for each member of the family to squeeze into an inflatable dinghy for the short but perilous passage from the Turkish coast across the Aegean to the Greek island of Kos and -- maybe -- to a new life in the EU.

Turkish coastguards have rescued almost 18,300 migrants in the Aegean Sea in the last month amid a drastic rise in the number attempting the maritime crossing to the EU, the government said on Monday.

Between July 17 and August 17 2015, 18,296 "irregular migrants" were rescued by the Turkish coastguard, the government said in a statement in response to an AFP inquiry.

Turkish Prime Minister Ahmet Davutoglu on Monday said he had exhausted all options to form a coalition government, leaving the country facing snap elections just months after the June 7 polls.

The ruling Justice and Development Party (AKP) lost its overall majority in the June 7 legislative polls for the first time since it came to power in 2002, in a major setback for its co-founder President Recep Tayyip Erdogan.

Turkey's embattled lira hit a new historic low in value against the dollar Monday as investors took fright at ongoing political uncertainty and the prospect of early elections.

The lira slid to a new low of 2.862 to the dollar, losing 1.06 percent on the day.

Turkey and United States said on Sunday that Washington would withdraw its Patriot missile batteries from the country in October after bolstering Ankara's air defenses against threats from Syria's civil war.

The NATO mandate for the two-year mission will run out in October and will not be renewed, but the U.S. is prepared to return Patriot assets and personnel to Turkey within one week if needed, a joint Turkish-U.S. statement said. 

One Turkish soldier and three suspected members of the outlawed Kurdistan Workers' Party (PKK) were killed in eastern Turkey in new violence blamed on the Kurdish rebels, the state media said Sunday.

Fighting erupted in the early hours of Sunday near Kagizman town in eastern Kars province during a security sweep of the area, the official Anatolia news agency reported.

Three Turkish soldiers were killed on Saturday in a bomb attack blamed on Kurdistan Workers' Party (PKK) rebels in the east of the country, the army said.

The deaths were the latest in an escalating cycle of violence between Turkish security forces and Kurdish rebels that has left a 2013 ceasefire in tatters.
