Idi Amin Dada, the deposed Ugandan dictator, is unwelcome at his home-in-exile in Saudi Arabia, Arab diplomats said today.

‘His nagging desire to recapture power in Kampala has embarrassed his Saudi hosts and put his African sympathizers on the spot,’ said a Riyadh-based Arab Ambassador, who insisted on anonymity.

Mr. Amin, 61 years old, slipped out of Saudi Arabia this month and turned up Jan. 10 in Zaire on a false passport with one of his sons.

Uganda’s Government has demanded his extradition, probably to appear before a presidential commission investigating atrocities under previous regimes.

Mr. Amin, a former master sergeant who became one of Africa’s most ruthless dictators, was ousted from his East African nation in April 1979. He was granted political asylum in Saudi Arabia in 1980.

Saudis Supported Family

Saudi Arabia housed him and his family in a Jidda villa, giving him a monthly allowance, two cars and a telephone, on the understanding that he shun the press and quit politics. But according to people close to Mr. Amin, the dream of retaking power has haunted him. He apparently believed Saudi Arabia would use its influence to reinstate him as president of Uganda.

His wife and 22 of his children still are in the Saudi Red Sea port of Jidda, but the Arab diplomat said he had finally alienated his hosts by traveling to Zaire on false documents.
‘Idi Amin has gone too far this time, stretching the rules of Saudi hospitality to the limits,’ the ambassador said. ‘He has been quietly looked upon as persona non grata and won’t be allowed to return.’

Zaire refused to accept Mr. Amin and sent him to Senegal to catch a flight to Riyadh. But Saudi officials barred him from boarding the plane, and the Senegalese returned him to Kinshasa, the capital of Zaire.

His predicament has drawn no public comment from Saudi officials.

Three Cabinet ministers, a former Vice President and 14 other men were charged with treason today, accused of plotting to overthrow the eight-month-old Government of President Yoweri Museveni.

If these 18 Ugandans are convicted, they could face the death penalty.

The most prominent defendant is Paulo Muwanga, who was Vice President under Milton Obote. Also accused were Commerce Minister Evaristo Nyanzi, Energy Minister Andrew Kayiira and Environment Minister David Lwanga. They were among leaders of anti-Obote guerrilla and political groups invited to join the Government after Mr. Museveni’s National Resistance Army won a five-year guerrilla war in January.

Ugandan rebel forces were reported today to have further consolidated their control of the country, seizing Uganda’s second largest city. Western diplomats here said the rebels, who on Sunday overthrew the military Government of Maj. Gen. Tito Okello, overran the city, Jinja, at midday after a major battle. The city, where many of Mr. Okello’s bedraggled troops fled after being forced from Kampala, Uganda’s capital, is the site of the landlocked country’s major hydroelectric power station at Owen Falls and the point where the major road and rail links to the Kenyan coast cross the Nile.

City Called Key to Control Diplomats had said earlier that the rebel movement, known as the National Resistance Army, needed to take control of Jinja, 50 miles east of Kampala, to restore essential services that were disrupted during the fighting in Kampala and by fleeing Government troops. [Some troops fled to the Murchison Falls game park, where they were reported to be slaughtering rare wild animals for food just as Idi Amin’s men did seven years ago, according to reports reaching the capital quoted by Reuters.

[The Murchison Falls park, named after the spectacular waterfall where the Nile is forced through a 22-foot-wide rock gap and falls more than 100 feet, was heavily populated with elephants, lions, buffalo, antelope and other species in the 1960’s.

Museveni has pledged to form a broad-based democratic government and punish former junta officials for crimes against the people.

Leaders of a rebel movement announced today that they had overthrown the military Government of Uganda after seizing control of Kampala, Uganda’s capital.

Leaders of the rebel movement, the National Resistance Army, said at a news conference in Nairobi that their group was now the legitimate Government and vowed to take control of the entire country.

Maj. Gen. Tito Okello, who became Uganda’s head of state after staging a military coup last July, was reported by a Kenyan newspaper today to have said that he would counterattack and fight on.

Soldiers Surrender and Retreat Western diplomats and other sources said, however, that thousands of the military leader’s troops were surrendering, others were retreating north toward the Sudan and east toward Kenya, and still others were fighting among themselves over whether to stage a counteroffensive or to lay down their arms.

Ugandan rebel forces advanced to the outskirts of Kampala today and an army barracks in the capital was reported shelled.

The developments came a day after Government soldiers went on a rampage in which six people, including four schoolchildren, were killed.

A source in Uganda’s military Government said guerrillas from the National Resistance Army had moved to within three miles of Kampala from positions farther to the southwest.

Foreign Minister Olara Otunnu of Uganda said at a news conference here today that in the last six days the National Resistance Army rebels had mounted an eight-pronged offensive in an attempt to wreck their peace agreement with the Government. The pact, signed Dec. 17, was designed to end a five-year-old civil war.

Uganda announced today that it was offering the country’s main guerrilla group an equal say with the army on the governing military council and vice chairmanship of the body.

The Government called the offer today to the National Resistance Army proof of its commitment to end a four-and-a-half-year civil war that has killed, displaced or maimed thousands of people in the East African nation.

The proposals were outlined in a statement issued in Nairobi and broadcast over the Ugandan radio at the opening of the fourth round of peace talks. Uganda’s military leader, Lieut. Gen. Tito Okello, and the commander of the insurgents, Yoweri Museveni, led their delegations.

General Okello arrived in Nairobi this morning to take command of the delegation from his Defense Minister, Col. G. Wilson Toko, who led the Government side in previous sessions. Mr. Museveni had not taken part since the first two rounds in late August and early September.

The guerrillas are the largest and best organized of several bands of insurgents who began fighting the civilian Government of President Milton Obote early in 1981.

Seventeen Government soldiers have been killed and 82 captured in clashes at Katonga Bridge, 60 miles southwest of Kampala, rebels said today.

A spokesman for the National Resistance Army said there had been no casualties on the rebel side in fighting at the bridge over the last few days.

The guerrillas, who are fighting Uganda’s new military Government, will hold onto Katonga Bridge, the rebels’ eastern front, at all cost, the spokesman said by telephone from Masaka, the country’s third largest town.

The bridge is on the road that links Kampala to Masaka, which has been cut off by the rebels for three weeks.
