Can follow Sierra Leone Amnesty Militiamen loyal to the government of Sierra Leone say they've killed almost seventy Liberian fighters supporting remnants of the ousted military junta.

The pro-government militiamen in Sierra Leone say those killed were among three-hundred Liberian fighters who were ambushed yesterday as they crossed into the country.

The Nigeria-led intervention force, ECOMOG, has accused Liberian militiamen of fighting side-by-side with Sierra Leonean rebels in the border area between the two countries.

The Liberian government has denied any involvement.
