BEIRUT | AP | 13 Jul 2013 :: Activists say Syrian rebels and fighters from an al-Qaida-linked group have turned their guns on each other and are fighting for control of a key checkpoint in the northern city of Aleppo.
The Britain-based Syrian Observatory for Human Rights says Saturday’s clashes are focused on the strategic checkpoint in Aleppo’s Bustan al-Qasr district.
