The US military in Africa says it has sent 40 additional soldiers to South Sudan’s capital, Juba, to help secure American personnel and facilities in the war-torn city.

Africom spokeswoman Cpt. Jennifer Dyrcz said the US troops deployed at the request of the State Department, amid a tense cease-fire which has held since Monday night.

In five days of fighting in the capital President Salva Kiir’s forces ousted those loyal to First Vice President Riek Machar from one of their bases. The fighting left hundreds dead in the capital and aid workers said bodies remain in the streets.

The US Embassy in Juba said flights will be organized for all US citizens wishing to leave South Sudan. The embassy is also evacuating non-essential staff.
