The M23 rebel group of the Democratic Republic of Congo demanded a ceasefire before the resumption of peace talks.
The M23's political leader, Bertrand Bisimwa told AFP on Thursday:
"Our delegation will return to Kampala if -- and only if -- the government agrees to sign a ceasefire with us immediately."
According to Bisimwa, the DR Congo government forces and the Democratic Forces for the Liberation of Rwanda (FGLR - a Hutu rebel group), were advancing on two fronts. Bisimwa added, "and we don't know what their intentions are."
The government rejected any association with the FDLR, and dismissed reports that the army had moved on the ground.
Military spokesperson Olivier Hamuli told AFP:
"It's false, it's propaganda. We could never join forces with an armed group, and even less so with FDLR, and we're not preparing an offensive against them [M23]."
