South Sudanese President Salva Kiir and rebel commander Riek Machar signed a cease-fire deal on Friday after coming under growing international pressure to end ethnic fighting that has raised fears of genocide.

Friday's deal was made at a meeting in Ethiopia that was the first time the two men had met face to face since violence erupted in December following a long power struggle. Kiir and Machar, both Christians, shook hands and prayed together.

The men agreed that a transitional government offered the "best chance" to take the country toward elections next year, though there was no immediate decision on who would be part of an interim administration.
