A Cambodian UN-backed tribunal formally charged another two former Khmer Rouge cadres with crimes against humanity on March 3.

Meas Muth and Im Chaem, both in their seventies, were charged in absentia by international co-investigating Judge Mark Hampton over their involvement with the regime that led to the deaths of almost two million Cambodians in the 1970s.

The court has alleged that Meas Muth, an ex-navy commander, sent captives to a torture centre whilst Im Cheam, a female former district official, ran a forced labour camp.

The two have been accused of crimes against humanity and homicide.

Decisions on whether these cases will end up with indictments or dismissals are expected next year, according to court spokesman Lars Olsen.

Since the tribunal was established in 2006, it sentenced Kaing Guek Eav, former chief at Tuol Sleng prison, to life imprisonment in 2010.

Most recently, in August 2014, Nuon Chea, 88, and Khieu Samphan, 83, received life sentences for crimes against humanity. The pair have since appealed the verdict. Currently, they are undergoing a second trial focusing on the killing of ethnic Vietnamese and Muslim minorities, forced marriage, and rape.-VNA
