The president of South Sudan has defended the deployment of dozens of heavily armed troops around the residence of the First Vice-President Riek Machar.
Salva Kiir described it as "normal practice", designed to protect the former rebel leader.
Mr Machar condemned the move, saying it "creates doubt" that the fragile peace process can succeed.
He has accused government forces of attacking his positions in Upper Nile and Unity states, in the north of the country, in recent weeks.
The United Nations has urged the two sides to negotiate to try to stop South Sudan sliding back into full civil war.
Soldiers had encircled Mr Machar's house from Sunday evening until Monday, after he rejected President Kiir's directive on the formation of a national army.
It's a key part of the peace deal the pair signed in 2018 following five years of civil war. But progress been hampered by mistrust among political leaders, inter-communal fighting and insecurity - and tensions are high as the country prepares for a general election next year.
