Ugandan police raided two newspaper offices and two radio stations Monday, after reports of a falling out among army generals over whether the president's son is to succeed him.

"Police ordered our operations shut down under the pretext of carrying out a search," said Alex Asimwe, managing director of The Daily Monitor, one of the country's main daily newspapers.

Uganda has suspended its hunt for Lord's Resistance Army chief Joseph Kony in Central African Republic after Seleka rebels took control of the country, an army spokesman said Wednesday.

"We have temporarily suspended operations against the LRA until further notice," army spokesman Felix Kulayigye said.

Democratic Republic of Congo's M23 rebels and government delegations met separately Saturday with Ugandan mediators, a day ahead of a hoped-for resumption of direct talks, Ugandan officials said.

"The two delegations are here finally and we are hoping for a (face-to-face) session tomorrow (Sunday)," said Ugandan defense ministry spokesman Paddy Ankunda.

Democratic Republic of Congo's M23 rebels on Wednesday demanded Kinshasa sign a formal ceasefire, accusing officials of dragging out peace talks to bolster the army's position on the ground.

"The government is refusing to sign a ceasefire," said the rebels' political chief Jean-Marie Runiga told Agence France Presse.

The inability of U.N. peacekeeping forces to prevent conflict in eastern Democratic Republic of Congo is shameful, Ugandan President Yoweri Museveni, a key broker in the crisis, said at a summit on Saturday.

"It is a very big shame," Museveni said of MONUSCO, during a summit of the southern African bloc SADC in the Tanzanian economic capital Dar es Salaam. "It is some sort of military tourism."

The M23 rebels in the Democratic Republic of Congo said Tuesday they would only withdraw from Goma if the government meets their demands, despite earlier announcing they would pull out of the key eastern city.

The M23 wants the government to dissolve the country's election commission and ensure freedom of movement for opposition leader Etienne Tshisekedi among other demands "before a pullout", political leader Jean-Marie Runiga told a press conference in Goma.

Regional leaders called on DR Congo rebel group M23 Saturday to end hostilities and leave a key eastern town they seized in a rampant advance that has sparked fears of a wider conflict.

The meeting of east African heads of state went forward without a key player -- Rwandan President Paul Kagame, whose country the United Nations accuses of backing the rebels -- and wrapped up after less than an hour.

Uganda maintained a threat to withdraw troops from international peacekeeping operations after U.N. talks on Monday over accusations that it has backed rebels in the Democratic Republic of Congo.

Uganda's Communications and Information Minister Ruhakana Rugunda told AFP his country felt "stabbed in the back" by a U.N. report which said Uganda and Rwanda have helped M23 rebels who are battling DR Congo government forces.

Canada's top diplomat blasted Iran for human rights violations and religious intolerance at a meeting Monday of world parliamentarians, drawing an angry response from Tehran's delegation.

Addressing 1,400 lawmakers at the gathering in Quebec City, Canadian Foreign Minister John Baird said Bahais and Christians in Iran were "consistently threatened with death and torture, simply for believing."

Uganda will contradict U.N. accusations that it supports the M23 rebel group in Democratic Republic of Congo, and does not fear threatened sanctions, Kampala's acting foreign minister said Saturday.

The U.N. Security Council said Friday it intends to sanction leaders of M23 and implicitly threatened Rwanda and Uganda, accused in a recent U.N. report of arming the movement.
