BEIRUT (AP) — Syrian rebels fully captured a northern town near the Turkish border on Tuesday after weeks of heavy fighting and attacked a regime air base in a neighboring province, activists said.

The air base is in Aleppo province, where opposition fighters have already captured three other large military bases in recent months. Rebels have also laid siege to the international airport in the city of Aleppo, Syria’s commercial capital, and launched an offensive on the police academy near the city.
