(CNN) -- Tens of thousands of Congolese refugees fled camps Tuesday in the Democratic Republic of Congo as rebel troops attacked government forces in the area, the U.N. refugee agency said.

Refugees move along a road Tuesday in Mugunga, near Goma, in the Democratic Republic of Congo.

A press release from the U.N. High Commissioner for Refugees said it didn't appear rebels had targeted the camps, but it reported some were looted after camp residents, classified as internally displaced persons, fled.

Roads to Goma, about 10 miles from the camps, were crowded with refugees and local residents fleeing the fighting, the UNHCR reported. Torrential rain made the movement even more difficult.

"The main road toward Sake was crowded with people; we had difficulties getting through," UNHCR field safety adviser Pierre Nazroo was quoted as saying in the agency's release. "Internally displaced people are moving from site to site, direction Goma."

UNHCR spokesman Ron Redmond said, "They have been living in extremely difficult conditions anyway. Now they have nothing but what they can carry."

Redmond added, "These are people in poor health; they are soaking wet because of the torrential downpours. They need shelter, they need water, they need a lot of assistance so we're going to have to move quickly to get that help to them because a lot of them are already in a weakened state."

While the Congolese government accused troops under rebel general Laurent Nkunda of staging the attack, a Nkunda spokesman denied the allegation, according to a report from the Integrated Regional Information Networks, a U.N.-affiliated news service.

The spokesman, Bwambale Kakolele, said Rwandan Hutu rebels who also operate in the area were behind the attack, that report said.

A spokesman for the U.N. military mission in the Congo said it was uncertain which group attacked the Congo army outpost near the village of Kishangazi, according to the U.N.-affiliated news service.

"We think it could have been insurgents close to Nkunda who attacked, but we cannot rule out the [Rwandan rebels]," spokesman Col. Pierre Cherayron was quoted as saying.

The UNHCR identified the affected camps as Mugunga I, Mugunga II, Lac Vert and Bulengo, saying about 28,000 had abandoned the first three camps and about 2,000 had left Bulengo.

The UNHCR said 375,000 Congolese in North Kivu province have been forced from their homes in the past year. In the past two months alone, 160,000 have fled their homes amid the fighting between renegade troops and government forces, the agency said.

North Kivu is in eastern Congo near the borders of Rwanda and Uganda.

Congolese President Joseph Kabila has tried to gain a cease-fire with the rebels in the area under Nkunda, but fighting continues as hard-liners among the rebels and in the government have blocked reconciliation efforts, according to the International Crisis Group, an nongovernmental organization looking for solutions to conflicts.
