Syria opposition groups set for crucial Doha meeting

Syrian opposition groups are preparing for a crucial meeting on Sunday in the Qatari capital, Doha, to discuss how to form a more united front.

The meeting could lead to a replacement for the Syrian National Council (SNC), the main opposition body in exile.

The SNC has been criticised as out of touch by rebel forces in Syria, and the opposition is also split ideologically.

The Doha talks come a day after rebels in northern Syria launched an offensive to try win control of a key airbase.
