Syria's embattled President Bashar al-Assad.

Beirut - Syria's opposition chief extended a hand on Monday to the regime of President Bashar al-Assad but said it was now up to him to take the next step towards dialogue between Syria's warring parties.

In an interview with pan-Arab channel Al-Jazeera, Ahmed Moaz al-Khatib also said negotiating with regime officials would not be treason, as his detractors had said after his surprise announcement last week he was willing to talk. - Sapa-AFP
