Jacob Zuma arrives in Libya to negotiate ceasefire

An African Union mission has arrived in Libya to try to negotiate a ceasefire between rebel forces and those loyal to Col Muammar Gaddafi.

South African President Jacob Zuma was greeted by large crowds on his arrival in the Libyan capital, Tripoli.

The AU delegation will also visit rebel representatives in Benghazi.

The BBC's Jon Leyne said the leaders faced challenges in negotiating a "real ceasefire" from both sides of the conflict.
