JUBA - The death toll from fighting in South Sudan's capital Juba has climbed to 272 people, including 33 civilians, a source at the country's ministry of health told Reuters on Sunday.

The fighting broke out last week between troops loyal to President Salva Kiir and vice president Riek Machar.

Both men have said they did not know what had triggered the latest violence between their factions.

At least five soldiers were killed on Thursday in similar clashes between the two sides.

Africa's newest nation is emerging from a two-year civil war which started in December 2013 after Kiir sacked Machar as vice president.

The conflict was largely fought along ethnic lines with Kiir mostly drawing support from his Dinka tribe while Machar was backed by his Nuer tribe.

A peace agreement last August ended the war but Kiir and Machar have yet to integrate their forces, a key part of the agreement.
