Three former employees of a Canadian mining company should face prosecution for complicity in war crimes, a military judge has ruled in the Democratic Republic of Congo...Representatives for Anvil, which is incorporated in Canada but also has offices in Australia, were not available for comment. Last year, Anvil confirmed it loaned a plane and vehicles to the army, but said it ''had absolutely no choice'' but to accede to a government request for logistical support. ''When the army arrives with AK-47s ... you give them what they want,'' said Anvil spokesman Robert LaValliere, recalling that troops had commandeered vehicles at gunpoint in a previous clash with rebels earlier that year. He added that companies are obliged by law to comply with Congolese government requests. But after a long investigation into the killings, torture and rape of villagers by the soldiers, the Congolese military prosecutor found the Anvil employees ''voluntarily failed to withdraw'' the vehicles, and has asked that the three be formally charged.
