The US has expressed "alarm" over the escalating tensions in South Sudan.
It mentioned previous incidents in Upper Nile state between forces loyal to opposing groups, as well as "inflammatory rhetoric" that was "counterproductive" to peace.
The US State Department issued a statement urging President Salva Kiir and First Vice-President Riek Machar to follow through on their commitments under the 2018 peace agreement.
It said that skirmishes and the opposition's departure from a group overseeing the peace process were jeopardizing the accord.
It urged the two leaders to "do everything possible to de-escalate tensions," emphasizing that they were both to blame for the situation's deterioration.
Following five years of civil war, President Kiir and Mr. Machar reached a peace pact in 2018.
However, mistrust among leaders, intercommunal violence, and insecurity have impeded its execution.
