An Israeli trooper has been kept after a video rose demonstrating to him evidently shooting a Palestinian in the head as he lay injured and unmoving on the ground.

The Palestinian was soon proclaimed dead. He was one of two aggressors who had before cut another Israeli fighter in the West Bank city of Hebron.

The Israeli military said the shooting was a "grave rupture of IDF (Israel Defense Forces) values".

The officer has not been distinguished.

"In light of the underlying test into the episode, a military police examination has been dispatched," the Israeli armed force said on Thursday.

The shooting happened minutes after two Palestinian assailants wounded an IDF officer at a checkpoint in Hebron.

The Palestinian appeared in the video was shot and injured amid the assault.

Footage taped by an observer then demonstrates to one of Israeli officers seeming to focus on and discharge a shot into the Palestinian's head.

Authorities said the Israeli officer wounded before was in stable condition.

No less than 29 Israelis have been executed in a flood of wounding, shooting or auto slamming assaults by Palestinians or Israeli Arabs since October.

More than 180 Palestinians - generally aggressors, Israel says - have likewise been executed in that period.

The aggressors who have been murdered have been shot dead either by their casualties or by security strengths as they completed assaults. A few assailants have been captured.

Different Palestinians have been slaughtered in conflicts with Israeli troops.
