A group of rebel militias in the Democratic Republic of Congo (DRC) says it has suspended participation in a 2008 cease-fire agreement.

The rebel groups have released a statement citing a number of reasons for their decision, including the government's arrest of some of their members.

In January 2008, rebels in the eastern DRC signed a peace accord with the government aimed at ending years of fighting in the region.

The country's five-year civil war formally ended in 2003.  However, militias and rebel groups have remained active in some eastern areas, especially North Kivu province.

Bloomberg news reports that Congo's communications minister has dismissed the militias' statement.  The news agency quotes Lambert Mende as saying the militias think they "are in charge of the peace process, but they are not."
