Final round of Aleppo evacuations underway

An Associated Press TV crew said four buses from the opposition's last foothold in the city arrived to the western Aleppo countryside Wednesday, marking the first successful evacuation in over 24 hours.

Syrian state media said on Tuesday evening that "differences among terrorist groups" were holding up the evacuations from Aleppo and from two rebel-besieged Shiite villages in the country's north, Foua and Kfarya.

[...] Tuesday, the U.N. humanitarian aid agency said Syria's government authorized U.N. plans to send about 20 staffers to monitor evacuations from eastern Aleppo.

Elsewhere in northern Syria, fighting between the Islamic State group on one side, and Turkish forces and Syrian opposition forces on the other, killed four Turkish soldiers, according to the state Anadolu news agency.

Turkey sent ground troops into northern Syria in August to support Turkey-backed Syrian opposition forces in clearing a border area of Islamic State group militants and to curb Kurdish territorial expansion.
