Ugandaâ€™s government says it doubts rebel leader Joseph Kony is serious about peace after he purportedly sent a letter asking for forgiveness and calling for talks, British Broadcasting Corporation reports.
Government official Henry Okello-Oryem said a telephone conversation arranged with Kony had failed to materialise.
The letter reportedly saw Kony say his Lordâ€™s Resistance Army rebel group was committed to â€œend this war.â€
It has waged an insurgency for more than 20 years.
It is notorious for abducting children to serve as sex slaves and child soldiers.
Kony is wanted by the International Criminal Court for alleged war crimes.
Several thousand African troops, backed by 100 US special forces, have been hunting him and other fighters of the LRA across the region.
The US has offered up to $5m (Â£3.3m) for leads resulting in his arrest.
Talks between the government and LRA collapsed in 2008 after the ICC refused to yield to Mr Konyâ€™s demand to drop the arrest warrant.
â€œI want to assure the people of Uganda that, we are committed to a sustainable peaceful political settlement of our long war with the government of (President Yoweri) Museveni,â€ Kony is quoted as saying in the purported letter, published in Ugandaâ€™s privately owned Daily Monitor newspaper.
â€œWe are willing and ready to forgive and seek forgiveness, and continue to seek peaceful means to end this war which has cut across a swathe of Africa for the people of the Great Lakes and the Nile-Congo Basin to find peace.â€
