ANKARA, Turkey (AP) — As Kurdish rebels in northern Syria rack up wins against the Islamic State group, Turkish media is abuzz with talk of a long-debated military intervention to push the Islamic militants back from the Turkish border — a move that will also outflank any Kurdish attempts to create a state along Turkey's southern frontier. Pro-government newspapers are rife with purported proposals, ranging from loosening the rules of engagement to give Turkish troops a freer hand to fire into Syria, to a tanks-and-troops invasion aimed at occupying a 110-kilometer (70-mile) long, 33-kilometer (20-mile) wide buffer zone. In a telephone interview, Stein said the new talk of action was due in part to dramatic Kurdish gains in Syria, where rebels have scored a series of victories against Islamic State, most notably in the border town of Tal Abyad. Most seriously, any fighting in Kurdish areas of Syria risks derailing the peace process with Kurdish rebels in southeastern Turkey, overturning a key achievement of Erdogan's leadership and potentially spreading violence across the country.
