UN peacekeeping chief Jean-Pierre Lacroix is calling for action against those who violate the ceasefire in South Sudan. It comes just days before the third round of peace talks are set to take place in Ethiopia. CGTN's William Denselow reports from UN headquarters in New York.

Addressing the United Nations Security Council, Jean-Pierre Lacroix said that the prospect for elections in South Sudan are currently unrealistic given the situation on the ground.

The UN's Under-Security-General for Peacekeeping added that 4.3 million South Sudanese are displaced and that 100 aid workers have been killed since the conflict began in 2013. Lacroix says there have been disturbing reports of rape and gang rape and that this must be brought to an end.

In late April the UN's mission in South Sudan UNMISS released a press release expressing its deep concern about a surge in violent clashes in regions including Unity and Central Equitorias. The concern at the UN is that this escalation could derail the peace process. As chair of the South Sudan Sanctions Committee- Poland's UN Ambassador Joanna Wronecka briefed the council on the panel of expert's final report.

She repeated the panel's call for an arms embargo and urged the council to slap sanctions on more people and entities.

South Sudan's UN representative accused the panel of bias against the government. Adding that an arms embargo won't provide peace to the country and risked prolonging the conflict. William Denselow, CGTN, New York.
