Afghan presidential candidates sign unity deal

A deal aimed at forming a government of national unity in Afghanistan has been signed at a ceremony in Kabul, the BBC reports on Sunday.

The signing - broadcast live on national TV - comes after months of wrangling following presidential elections in April and June.

Under the deal, Ashraf Ghani becomes president while runner-up Abdullah Abdullah nominates a CEO with powers similar to those of prime minister.

The final result of the bitterly contested poll is due to be announced.
