JUBA, Aug. 24 (Xinhua) -- The United Nations Mission in South Sudan (UNMISS) on Monday strongly condemned an ambush on its patrol traveling to Pajut, Jonglei State, which left two peacekeepers dead.

"Two peacekeepers were killed in the attack, while seven others were injured, including three peacekeepers, two South Sudan National Police Service personnel and two civilian staff," UNMISS said in a statement issued in Juba, the capital of South Sudan.

Anita Kiki Gbeho, special representative of the UN Secretary-General and head of UNMISS, said that such deadly violence targeting personnel serving to support peace in South Sudan is completely unacceptable.

"I extend my deepest condolences to the family and loved ones of the peacekeepers who lost their lives and wish those injured a speedy recovery," Gbeho added, calling on relevant authorities to conduct a thorough and prompt investigation.

The UN mission said it has deployed a Quick Reaction Force to secure the area and support emergency response operations.
