The US Embassy in South Sudan called on its compatriots in the capital city of Juba to be vigilant after the violent clashes between the forces loyal to President Salva Kiir and First Vice President Riek Machar, the mission's statement issued on Sunday said.

The situation in Juba has significantly deteriorated. There is serious ongoing fighting between government and opposition forces, including near the airport, UNMISS locations, Jebel and elsewhere throughout Juba. U.S. citizens in Juba should remain vigilant. You should shelter in a safe location, preferably away from doors and windows, and avoid non-essential movements," the statement posted on Facebook reads.

The South Sudan armed ethnic conflict erupted in December 2013, a year-and-a-half after the nation gained independence from Sudan, when President Kiir blamed First Vice President Machar of preparing a military coup. The conflict forced more than a million people to flee their homes.

In August 2015, Kiir and Machar signed a peace deal for the formation of the Transitional Government of National Unity.
