Juba

UN representatives reported heavy exchanges of gunfire near their headquarters in the suburb of Jebel.

The clashes follow days of fighting between supporters of President Salva Kiir and Vice-President Riek Machar.

The violence has raised fears of renewed instability, with a 2015 peace deal failing to quell unrest.

Heavy gunfire was reported on Sunday in the Gudele and Jebel suburbs of Juba, near a military barracks occupied by troops loyal to Mr Machar.

Julius Kilong Ramoi said Thursday his son, Peter Julius Moi, a reporter for the Corporate Weekly, was shot twice in the back Wednesday night. 

The international Journalists' rights group Committee to Project Journalist quoted Kiir as threatening journalists on Sunday. Moi was shot dead near South Sudan's only brewery which had been the subject articles he had written recently.

Moi is the seventh journalist to be killed in South Sudan this year.
