Heavy explosions are shaking South Sudan's capital Juba Monday morning as clashes between government and opposition forces entered their fifth day, ABC news reported.

Widespread shooting prevented residents from moving around. Clashes coincide with the fifth anniversary of South Sudan independence day.

Clashes between forces loyal to President Salva Kiir and his deputy Riek Machar have resulted in the killing of more than 270 people so far.

A "massive explosion" hit shortly after 9 a.m. followed by further blasts in the Tomping area of Juba, home to embassies, the airport and a U.N. base, said an aid worker.

Explosions and "very heavy gunfire" sounding "like popcorn," was reported by a resident in the Gudele area, who insisted on anonymity for safety.

The United Nations Mission in South Sudan reported on Twitter that clashes restarted near its compound in Jebel, where some 30,000 civilians have taken refugee. The opposition also has a base near Jebel and their leader, First Vice President Riek Machar, also has his home there.
