KAMPALA, April 5 (Xinhua) -- The leader of Uganda's Lord's Resistance Army (LRA) rebels has crossed from the Central African Republic to the Democratic Republic of Congo (DR Congo) to reorganize fighters and search for arms, a Ugandan army spokesman said on Monday.

Citing LRA defectors, Lt. Col. Felix Kulayigye told reporters that Joseph Kony crossed to northeastern DR Congo to dig up the arms cache left behind after his base in Garamba forest was bombarded in a Ugandan-Congolese military offensive in December 2008.

"Kony had comeback to retrieve hundreds of gumboots and guns he had hidden in Camp Swahili," he said while parading LRA's political commissar Solomon Patrick Okello who was captured on March 30 by Ugandan troops in Sudan.

Kulayigye said the rebel leader, who is wanted by the International Criminal Court for war crimes and crimes against humanity committed in northern Uganda, keeps moving between DR Congo and the Central African Republic.

Okello who claimed was on his way to Uganda to deliver a message from Kony to resume peace talks with government said that he left Kony in DR Congo with about 200 fighters
Kulayigye said although Kony is no longer a threat to Uganda, he still remains a big threat to the region's stability.

"Kony is a regional problem that should be dealt with decisively. As long as Kony is free, there is going to be insurgency in this region," he said.

He said the rebel group last week killed 10 people and abducted 13 others in northeastern DR Congo.

This killing came at a time when the New York based Human Rights Watch released a report detailing how the LRA killed at least 321 civilians and abducted 250 others in the Makombo area of Haute Uele district in northeastern DR Congo. The massacre is reported to have taken place in December.

LRA fighters have been on the run since the December 2008 joint military offensive aimed at capturing Kony after he refused to sign a two year negotiated peace deal with the Ugandan government.

They have been moving in the jungles of northeastern DR Congo, southern Sudan, and the Central African Republic.

The rebel group's guerrilla-style warfare of more than 20 years has left tens of thousands of people dead and 2 million others homeless in northern Uganda, before the army in 2006 pushed it to southern Sudan and eventually northeastern DR Congo.
