The United Nations peacekeeping mission in Congo says that three people working for the organization have been kidnapped in Congo's east.

U.N. Congo spokesman Sylvestre Kilolo said Friday that one Zimbabwean and two Congolese had been in the region investigating an area for de-mining. He said they were preparing to return to Goma on Thursday when they were kidnapped. They were taken into the forest and their vehicle was left on the road.

Congolese soldiers have been fighting in this region against Rwandan rebels, known by their French acronym FDLR. Eastern Congo has been plagued by a myriad of armed rebel groups since the 1994 Rwandan genocide.

The Congolese military and the U.N. peacekeeping mission successfully fought another rebel group known as the M23, which opposed the FDLR.
