UNHCR spokesperson Ravina Shamdasani said a UN official had seen 14 bodies in a mass grave in Bentiu and another 20 at a riverside nearby.
But she said 75 SPLA soldiers, all Dinka, were unaccounted for there and were feared dead.
The other two reported mass grave sites are at Jebel-Kujur and Newside, near Eden, in Juba.
Security Council vote
President Kiir earlier told journalists in Juba that his forces had "retaken Bor and are now clearing whatever forces that are remaining there".
Bor, 200km (125 miles) north of Juba, had been one of the major successes for the rebels. They are believed to still be in control of Bentiu, where some 7,500 civilians have sought refuge in a UN camp.
Radio Tamazuj said government troops of the Sudan People's Liberation Army had launched attacks on positions held by Nuer commander and army defector Peter Gadet on Tuesday afternoon in Bor.
Some reports said there was still fighting near the airport.
Mr Kiir said there was also fighting in the town of Malakal and that his troops were "ready to capture Bentiu".
President Kiir and Mr Machar have both said they are willing to talk.
However, Mr Machar has said his detained political allies must first be freed, while Mr Kiir says there should be no preconditions.
Mr Machar told Radio France Internationale he had formed a delegation for talks and that they would probably be held in Ethiopia.
He said: "We want a democratic nation. We want democratic free and fair elections. We want Salva Kiir to call it a day."
Mr Kiir has accused Mr Machar, who he sacked in July, of plotting a coup. Mr Machar denies he is trying to seize power.
UN Secretary General Ban Ki-moon has called for an increase in the UN's peacekeepers from 6,800 to about 11,800. A Security Council vote on the resolution is expected later on Tuesday.
Sudan suffered a 22-year civil war that left more than a million people dead before the South became independent in 2011.
