Three people were killed in the eastern Democratic Republic of Congo in a  machete attack blamed on rebels from neighboring Uganda, local authorities said Tuesday.

The attack, which was repelled by the army, took place in the restive North Kivu province, where rebels from the Allied Democratic Forces and National Army for the Liberation of Uganda (ADF-NALU) have been accused of hacking scores of civilians to death since October.

Six U.N. peacekeepers from Ukraine were arrested in the Democratic Republic of Congo Wednesday for illegally being in possession of Congolese military uniforms.

The six were detained at Goma airport in the country's restive east along with the supplier of the uniforms, a Congolese man, according to Lieutenant Colonel Olivier Hamuli, a spokesman for the Congolese army (FARDC).

Ugandan priest John Ssenyondo loved his adopted country of Mexico and preached against violence until his body was found in a mass grave between fields of corn and beans.

Six months after he was abducted, Ssenyondo was identified among 13 bodies discovered by local people in the southern state of Guerrero, a state reeling from a wave of gang violence.

Uganda's Lord's Resistance Army rebels have launched a string of attacks across central Africa with a "steady increase" in abductions, the United Nations said in a report seen Thursday.

The elusive jungle insurgents, who raid villages and enslave residents, have abducted 432 people so far this year, a "steady increase" from last year and more than double the number in 2012, the report by the U.N. Office for the Coordination of Humanitarian Affairs (OCHA) read.

East African leaders warned South Sudan's warring rivals Thursday they must "come to their senses" to end almost 11 months of bloodshed amid renewed threats of international sanctions.

"There appears to be little appetite for peace, while the people of South Sudan continue bearing the full brunt of conflict," Ethiopian Prime Minister Hailemariam Desalgen said at a summit of regional leaders pushing for a peace deal.

Ugandan security forces committed "reprisal killings" in a remote mountain region earlier this year to crush tribal clashes, Human Rights Watch said Wednesday, highlighting reports of torture and mass graves.

Around a 100 people were killed, possibly more, in days of violence in the far western Rwenzori mountain range in July, when gangs armed with machetes, spears and guns launched a series of surprise raids to massacre neighbouring rivals, as well as raiding police and army posts.

Ministers appealed on Tuesday to panic-striken civilians in the volatile east of the Democratic Republic of Congo not to form militias to protect themselves after a string of massacres by Ugandan guerrillas.

Defense Minister Alexandre Luba Ntambo warned that self-defense groups could further complicate the already febrile situation around the town of Beni, where as many as 120 people have been slaughtered in five weeks of night-time rebel raids.

East African leaders met South Sudan President Salva Kiir on Wednesday in the latest push to end over 10 months of a civil war that has devastated the young nation.

Ethiopian Prime Minister Hailemariam Desalegn, Kenyan President Uhuru Kenyatta and Ugandan Prime Minister Ruhakana Rugunda visited the war-torn nation's capital on a one-day visit to discuss the "on-going peace process", a spokesman in Kiir's office told AFP.

Rebels killed 26 people with machetes in an attack in the east of the Democratic Republic of Congo as the authorities in Kinshasa demanded the recall Thursday of the top U.N. human rights official in the country.

The massacre in the town of Beni calls into question claims by the authorities that Ugandan rebels of the ADF-NALU, who have been terrorizing the east of Congo for the last two decades, were all but defeated.

Uganda has intercepted communications between militants in the east African nation and al-Qaida groups in north Africa requesting help in a planned attack on a major Kampala prison, the country's police chief has revealed.

The details of the plot were revealed a week after 10 members of Somalia's al-Qaida-linked Shebab rebels were remanded in custody after appearing in court on terror-related charges that prompted a major security swoop in the Ugandan capital.
