Two people were killed and four policemen injured Sunday in armed clashes between Sudanese government forces and a religious extremist group in central Sudan, official Sudan radio reported.

"Police and security units have attacked a camp for a group belonging to the extremist Al-Takfir Wal-Hijra (Anathema and Exile) Group, and the attack resulted in the killing of two members of the group and the injury of four policemen," the radio quoted Ahmed Abbas, governor of Sinnar State, as saying.

The security forces received information that Al-Takfir Wal- Hijra group has established a camp in a remote area inside Al- Dindir National Park, a natural animal reserve on the border between Sudan and Ethiopia, and have managed to arrest 25 members of the group, including their leader, according to the governor.

He said the group attacked in October a camp belonging to the Sudanese police at Al-Dindir area and seized arms and military equipment.

Extremist religious groups have been active in various areas in Sudan, which pushed the Sudanese government to establish a special anti-terrorism administration to monitor and combat the activities of these groups.
