South Sudanese rebels accused the army of attacking their positions on Friday just hours before a ceasefire deal agreed by the government and rebels comes into effect.
Rebel spokesman Lul Ruai Koang said "simultaneous attacks have been launched" by the army on rebel positions in the northern oil state of Unity, and in the volatile eastern Jonglei region.
But army spokesman Philip Aguer said he had "no reports of fighting", and that clashes in Jonglei had taken place before the deal was signed, when rebels attacked government forces.
Government and rebels pledged on Thursday to halt fighting within 24 hours and end five weeks of bitter conflict that has left thousands dead, but both sides have said they doubt the other can fully control the forces on the ground.
At sunset, Aguer said the country remained calm, with the ceasefire starting at 1730 GMT.
Koang alleged that South Sudanese government troops -- as well as Ugandan soldiers and rebels from neighbouring Sudan's war-torn Darfur region, the Justice and Equality Movement (JEM) -- had attacked rebel positions, warning they had the "right to defend themselves against this senseless aggression."
The ceasefire agreement was signed late Thursday in the Ethiopian capital Addis Ababa by representatives of South Sudan's President Salva Kiir and rebel delegates loyal to ousted vice president Riek Machar, and was greeted by cheers from regional peace brokers and diplomats.
US President Barack Obama, whose country provided crucial backing on South Sudan's path to statehood, described the deal as "a critical first step toward building a lasting peace".
UN chief Ban Ki-moon praised mediation efforts and called on both sides to "immediately implement" the agreement.
Kiir urged those rebels not under Machar's control to also respect the deal.
"Now that people have fought, people should come back to their senses and we sit down so that we can resolve this conflict through negotiation," Kiir said in address Friday.
Up to 10,000 people are believed to have been killed in the fighting pitting forces loyal to Kiir against a loose coalition of army defectors and ethnic militia nominally headed by Machar, a seasoned guerrilla fighter.
The fighting has been marked by atrocities on both sides with some 700,000 people forced from their homes in the impoverished nation.
There has also been a wave of brutal revenge attacks, as fighters and ethnic militia use the violence to loot and settle old scores.
Food to feed a quarter of a million people for a month has been looted from UN World Food Programme stores -- a staggering 3,700 metric tons -- with the agency warning that "humanitarian needs will continue long after the fighting stops".
More than 76,000 people are crowded inside UN peacekeeper bases across the country -- the highest number since the start of the conflict -- with most hesitant to leave the protection offered by the compound.
"No one I know is preparing to leave yet, they want to wait to see how things turn out," said David Choul, one of thousands squeezed into a former sports ground turned into a UN base in Juba.
Government delegation head Nhial Deng Nhial said he was sceptical of the rebels' capacity to rein in their forces, "given that the bulk of the rebels are made up of civilians" -- essentially any one of the countless people who have kept hold of their guns after decades of conflict.
But Rebecca Garang, widow of South Sudan's independence leader John Garang, and who stood with Machar to make a political challenge to the government in December before fighting began, dismissed such concerns.
"The ceasefire did not just come alone in isolation without Dr Riek (Machar) knowing what is going on... so I think he will be able to talk to all of them and control them," she told the BBC.
Daniel Deng Bul, who as the Episcopal Archbishop of South Sudan is one of the most senior spiritual leaders in the young nation, warned the deal would need support to be implemented.
"It creates a space for us to talk, a breathing space," Bul said. "Those who are brokering the agreement have to see it is properly secured."
