WASHINGTON: U.S. Secretary of State John Kerry on Tuesday urged sacked South Sudan vice president turned rebel leader Riek Machar to
eclare a ceasefire and talk to President Salva Kiir, a US official told AFP.
"He urged him to implement a ceasefire and begin mediated political talks," the official said, after Machar told French radio he was ready to begin talks on halting his country's mounting conflict.
