FREETOWN, Sierra Leone (AP) _ Two Western journalists were killed and two wounded by gunmen in an ambush Wednesday near the scene of recent fighting in Sierra Leone.

The wounded were treated at a hospital run by U.N. peacekeepers. Their injuries were not believed to be life-threatening.

The journalists were traveling in two vehicles and came under attack four miles east of Lunsar, an area that has been hotly contested in recent days by pro-government forces and rebels of the Revolutionary United Front, journalists said.

An American and a Spanish journalist were killed, according to colleagues who identified the bodies. A South African and a Greek were wounded. The names of the journalists, and their news organizations were withheld until families could be notified.

Pro-government forces in the West African nation have been fighting the rebel Revolutionary United Front, which took hundreds of U.N. peacekeepers hostage early in May and then launched an advance toward Freetown. Government forces have been slowly pushing the rebels away from the capital since then.
