The Centre for Peace and Justice (CPJ), a human rights entity in South Sudan, has deplored Wednesday’s attack on a civilian convoy along the Juba-Nimule highway.

CPJ’s executive coordinator blamed the East African regional bloc IGAD for failing to bring about a sustainable peace in South Sudan.

 “CPJ condemns the attack in the strongest terms possible. Those who will claim the responsibility should to be taken to court,” said Tito Anthony.

The rights body urged the international community to resuscitate the 2015 peace agreement.

Unknown gunmen on Wednesday morning ambushed a convoy of buses on the main road connecting South Sudan’s capital with the Ugandan border, killing at least four civilians.
