Syrian rebel forces occupied a second border post with Turkey on Sunday, three days after taking control of the frontier crossing of Bab al-Hawa, a Turkish diplomat told AFP.
The rebels are in control of the al-Salama outpost north of Aleppo since 0400 GMT, the diplomat said, speaking on condition of anonymity. It faces the southern Turkish border post of Oncupinar in the southern Kilis province.
By Saturday evening, a group of some 150 foreign fighters describing themselves as Islamists had taken control of the Bab al-Hawa border post, which fell under rebel control on Thursday, an AFP photographer said.
Some of the fighters said they belonged to Al-Qaeda in the Islamic Maghreb (AQIM), while others claimed allegiance to the Shura Taliban.
They were armed with Kalashnikov assault rifles, rocket launchers and improvised mines.
The fighters identified themselves as coming from a number of countries: Algeria, France, Egypt, Saudi Arabia, Tunisia, the United Arab Emirates and the Russian republic of Chechnya.
There are seven functioning border posts along the nearly 900-kilometre (560-mile) frontier.
