KINSHASA, April 5 (Xinhua) -- FARDC, the national army of the Democratic Republic of Congo (DR Congo), has regained control of the northwestern city of Mbandaka, but two UN personnel were killed in the clash, according to the government.

FARDC fought back hours after Enyele insurgents claimed to have taken the city and its airport in a surprise attack on Sunday morning.

"The army controls the city and the situation is calm," the governor of Equateur, Jean-Claude Baende, declared late Sunday, adding the Enyele insurgents were routed by the government forces who were pursuing the disbanded elements.

The governor, who has stayed in the capital Kinshasa since last week, said the incursion caused a heavy loss of lives and that some assailants were captured in the fighting. He did not give details.

The slain included a blue casque of MONUC, the UN peacekeeping mission in DR Congo, who was killed near the Mbandaka airport. The rebels held the airport only briefly. A civilian personnel of the mission also died in the fighting.

Meanwhile, hospital sources reported that they had received more than a dozen bodies.

Provincial Minister of Communication Rebecca Ebale said about 100 insurgents had requisitioned the ship "Malaika" owned by a company GAP before landing at the River Congo port of Bankita. They fought their way into the capital city of the province.

The rebel swoop came after Governor Baende announced the end of the months old Enyele rebellion on Tuesday.

Baende said "the Enyele rebellion" was no longer "an organized group, but just as small groups of residual elements who are searching for means of survival."

The armed youths from the Enyele tribe started attacking on Oct. 30 on the Boba tribe over the control of fishing points in Dongo. But when they were carried away by their victories, they formed a rebel movement and began to take away some other localities like Buburu in the Gemena district.

In early January, FARDC said it had taken control of Dongo, driving the insurgents out of the stronghold after fighting.

The Enyele insurgency has killed hundreds of people, including police officers intervening the tribal clash. It has also caused massive displacement. Up to 110,000 refugees fled to the Republic of Congo in the culmination of confrontations.

The influx of refugees across the River Congo has led to tensions between the two neighboring countries. In February, President Denis Sassou Nguesso of the Republic of Congo expressed fears about the refugees, wishing that they would quickly return to their own country to avoid conflicts with the local population. He also warned that "these refugees and the natives live in undesirable conditions regarding their health, food as well as their security. "

The tribal clash was the worst flare since the disbanding of the Tutsi rebel CNDP, which rendered 250,000 people homeless in the eastern province of North Kivu in late 2008 and early 2009.
