UNITED NATIONS (AP) — The United Nations says it has "paused" its support to a Congo military offensive against a rebel group after two Congolese generals linked to human rights violations were picked to lead the operation.

The spokesman for the U.N. secretary-general, Stephane Dujarric, confirmed the temporary halt Tuesday.

The U.N. has objected to two generals, saying they are known to be heavily involved in human rights violations and should be replaced before the U.N. supports the offensive.

"We are in constant high-level contact with the government and we are confident that a solution will be found," Dujarric said.

The U.N. estimates that 2,000 members of the FDLR militant group remain in Congo. They include Hutus who committed the 1994 Rwanda massacres.

Dujarric says the U.N. continues to support other Congolese military operations.
