The International Crisis Group said on Wednesday that Kony with his second-in-command Okot Odhiambo led a group of 200 LRA rebels and followers through the border into south Darfur and through northeast Central African Republic in August this year.

Kony is believed to be around Daffak area in southern Darfur where an ambush occurred September 2, according to information from the Liberation and Justice Movement.

"That seems to make sense with what the Ugandan army was saying. The pattern of attacks in the region and in northern CAR (Central Africa Republic) suggests it's accurate," ICG analyst Ned Dalby said.

The Ugandan army, deployed in Central African Republic since 2009 with its permission, "doesn't have permission from the Sudanese government to follow Kony in Darfur, and that's part of the reason why he is there," Dalby told AFP.

"He may also be hoping to receive support once again from Sudanese President Omar al-Bashir who in the early 2000 used the LRA as a proxy force against the south Sudanese rebellion."

The ICG analyst added that another group of 60 LRA rebels moved into the north of CAR from Ouanda Djalle, the scene of an attack on September 5, before heading towards Sudan.

"This group was led by a certain (Otto) Agweng, in charge of Kony’s body guard. That again would confirm the presence of Kony in the area," Dalby said.

Ugandan president Yoweri Museveni had already accused Sudan for abhorring LRA rebels and its leader.

“If the Sudanese want to accommodate him in Darfur, that makes no difference to us because they supported him much more in the past but whatever they gave him, we captured," Museveni stated in March.

Kony and his followers are accused of massacres, mutilation, forcibly enlisting boys as child soldiers, and taking girls as sex slaves.

Since 2008, LRA leader Kony has been on the run after regional States launched a chase to nab him after he rejected to sign a peace deal with Uganda. It is also alleged that his fighters have been moving in the forests of south Sudan, north-eastern Democratic Republic of Congo and the Central African Republic (CAR).

U.N-backed Congolese soldiers dismantled LRA training camps and disarmed some rebel fighters but the group continued its attacks on civilians in north-eastern DRC, Central African Republic and border regions in autonomous south Sudan.

Last week, the group attacked on the Central Africa Republic and abducted a number of girls.
