“The first vehicle of the Chemical Weapons Investigation Team was deliberately shot at multiple times by unidentified snipers in the buffer zone area,” the spokesperson said in a media note.

“As the car was no longer serviceable, the Team returned safely back to the Government check-point. The Team will return to the area after replacing the vehicle,” the UN added.

The Team, led by Swedish scientist Dr. Åke Sellström, is spending up to 14 days, with a possible extension, probing the alleged use of chemical weapons by the Government at Khan al-Asal, as well as two other allegations reported by Member States. The team is working in cooperation with the Organization for the Prohibition of Chemical Weapon (OPCW) and the UN World Health Organization (WHO).

“It has to be stressed again that all sides need to extend their cooperation so that the Team can safely carry out their important work,” the UN said in the note.

The peacekeeper was wounded when an unidentified armed group fired on an UNMISS patrol that was moving from Gurmuk to Pibor, UN spokesperson Eduardo del Buey told a news conference in New York.

“The peacekeeper has been evacuated to Juba for further medical treatment. His situation is stable,” he stated.

“The Mission strongly condemns this attack against its personnel and calls on all parties to respect the freedom of movement of UN personnel carrying out their mandate and to cooperate with the peacekeepers in their efforts to protect civilians and help establish a stable security environment in Jonglei state.”

Jonglei is the largest state in South Sudan and has been the scene of inter-communal violence since the country became independent from Sudan in July 2011.

The UN Security Council set up UNMISS in July 2011 to consolidate peace and security, and help to establish conditions for development in the world’s youngest nation.
