Syria’s President Bashar al-Assad speaks during an interview with Turkey’s Halk TV in Damascus, in this handout photograph distributed by Syria’s national news agency SANA on October 4, 2013. Assad has told Turkey it will pay a heavy price for backing rebels fighting to oust him, accusing it of harbouring “terrorists” along its border who would soon turn against their hosts. In an interview with Turkey’s Halk TV due to be broadcast later on Friday, Assad called Turkish Prime Minister Tayyip Erdogan “bigoted” and said Ankara was allowing terrorists to cross into Syria to attack the army and Syrian civilians.
