South Sudan’s rebel leader Riek Machar has returned to the country for the first time in more than two years - as part of a peace deal. His spokesman has told the BBC that Machar was now at rebel military headquarters in the eastern town of Pagak. He is expected in juba on Monday to resume the post of vice-president as part of last year's deal, while his deputy leader Alfred Ladu gore is already in the capital. Last week, more than 1,300 rebel troops were flown to juba as part of the terms of the peace deal signed in august last year. These forces are deployed to provide security for Machar, who said he would not come to take up his new position until these security measures were put into place.
