The Israeli military says it has launched an investigation after a local TV station aired video allegedly showing soldiers humiliating a bound and blindfolded Palestinian prisoner.

The pictures screened by Channel 10 show a man forced to repeat Hebrew phrases. Some referred to the Golani infantry brigade, while some were of a sexual nature.

The TV did not say where the incident occurred or show the alleged abusers but it said they were Golani troops who filmed the proceedings for their own amusement.

A military statement described the scenes shown in Thursday's broadcast as "grave" and condemned such behavior.

It said the TV broadcast was the first the army heard of the alleged incident and that "Investigative procedures were opened as soon as the footage was received."
