Kofi Annan plans to visit Damascus for the second time since the start of President Bashar al-Assad's crackdown on anti-government protestors began in March 2011. Annan, a United Nations-Arab League special envoy to Syria, could arrive as soon as next Wednesday, Al Arabiya reported, and he is expected to meet with government officials and opposition leaders.

Annan was the author of the six-point plan that was supposed to end 14 months of ceaseless violence in Syria. President Assad agreed to the plan last month, but he did not pull troops out of opposition areas by Annan's April 12 deadline and at least 900 people have been killed since.

U.N. chief Ban Ki-moon said in a letter to the Security Council that he still believes Annan is the best hope of ending violence in Syria, although he admitted to CNN's Christiane Amanpour on Thursday that at this time, we don't have any plan B.
