The rising civilian death toll in Syria is accompanied by mounting calls to arm the Syrian opposition. And Turkey, a NATO country that shares a long, rugged border with Syria, is often mentioned as a likely transit point.
Turkey has become increasingly critical of the Syrian regime, but Ankara is thus far reluctant to send significant arms across the border or use its large military to create a humanitarian corridor inside Syria.
The Syrian regime's heavy crackdown on dissent has led to a sharp plunge in relations with neighboring Turkey. But the regime does have its Turkish supporters — mainly members of the Alawite minority, the same Islamic sect Syria's ruling Assad family comes from. And that has resulted in complicated loyalties among some Turks, especially those along the border in southeastern Turkey's Hatay province.
