The Secretary-General of the United Nations says he is ‘deeply concerned’ by the renewed fighting in Nasir town of Upper Nile State.

Fighting broke out in Nasir yesterday morning between the government forces and the SPLA-In Opposition forces.

Ban Ki-moon has also called on the warring parties in South Sudan to stop the violence immediately.

The Secretary-General called on Dr. Machar direct his forces to immediately stop all offensive operations on Nasir and other areas in the country.

Mr. Ban also urged the Government of South Sudan to stop launching counter-offensive operations. He reminded them of their obligations under international humanitarian law.

He also warned the parties to the conflict of the consequences should any innocent civilian or United Nations peacekeepers come under harm from their forces.

Ban Ki-moon called on both parties to stop the violence immediately, reconvene political negotiations and demonstrate the political, which he says is necessary to find a peaceful resolution to the conflict.
