Syrian opposition leader Ahmed Moaz al-Khatib resigns
The leader of the opposition Syrian National Coalition (SNC), Ahmed Moaz al-Khatib, has resigned.
Mr Khatib wrote on Facebook that world powers had failed to help the rebels, and he could only improve the situation by working outside of the coalition.
Analysts say Mr Khatib believed the SNC was too heavily influenced by Islamists and foreign powers like Qatar.
