UN worker Clare Santry spoke to the BBC after returning from Juba in South Sudan. The UN says it is relocating all non-critical staff from the country amid escalating violence.
The country has been in turmoil since President Salva Kiir accused Mr Machar a week ago of attempting a coup.
Clare Santry, who is the communications officer for the UN mission in South Sudan, said there are "a lot of scared people there" and "we are not abandoning them".
