Syrian rebels said on Sunday they had captured a border crossing with Turkey at Bab al-Salam, north of the city of Aleppo - the third frontier point with Turkey they have seized in four days from President Bashar Al-Assad forces. 'The Free Syrian Army has taken control of the Bab al-Salam crossing, but Assad's forces are bombarding our positions from afar,' said Ahmed Zaidan, spokesman for an opposition group called the Higher Council of the Revolution's Leadership. Syrian rebels seized control of the Syrian side of the Bab al-Hawa and Jarablus crossings with Turkey last week, as well as at two crossings into Iraq, according to a report of Reuters.
