US State Department Acting Spokesman Mark Toner yesterday condemned the video footage released on Saturday which appeared to show armed troops summarily executing civilians, including women and children.
"Such extra-judicial killing, if confirmed, would constitute gross violations of human rights and threatens to incite widespread violence and instability in an already fragile country," Toner said in a statement.
"We call upon the government of the Democratic Republic of Congo to launch an immediate and thorough investigation, in collaboration with international organisations responsible for monitoring human rights, to identify those who perpetrated such heinous abuses, and to hold accountable any individual proven to have been involved."
The DR Congo government has discounted the authenticity of the seven-minute video, calling it a "ridiculous fake... worthy of scenes from a Rambo movie.
