JUBA, Aug. 1 (Xinhua) -- UN Under-Secretary-General for Peacekeeping Operations Jean-Pierre Lacroix arrived in South Sudan on Tuesday seeking to strengthen political solutions to the ongoing conflict and demand an end to hostilities.

The UN peacekeeping chief told reporters at Juba International Airport that he will hold talks with the government and other humanitarian actors to advocate for peaceful resolution of the conflict.

"I look forward to having discussions with the President of South Sudan, with members of the government to assess the security situation, to assess the political process and how we can help move that process forward," Lacroix said.

Lacroix will also use his three-day stay in South Sudan to undertake two field visits to areas affected by the conflict.

South Sudan has been embroiled in more than three years of conflict that has have taken a devastating toll on the people of South Sudan.

The peace pact signed in Addis Ababa in 2015 under intense international pressure was shattered again following renewed violence between rival government and opposition troops in the capital Juba in July 2016.

The conflict has since spread to other regions which enjoyed relative peace, causing mass displacement of least 3.5 million people from their homes, ethnic polarization and tribal violence that has killed tens of thousands of people.
