South Sudan rebel leader Riek Machar has said there must be proper negotiations before the rebels can agree to a truce with the government.

He was speaking after the government said it had agreed to an immediate end to fighting, in a declaration welcomed by east-African leaders in Nairobi.

At least 1,000 people have died in ethnic violence in less than two weeks.
