Israeli Defence Minister Avigdor Lieberman yesterday said a soldier who shot a Palestinian along the Gaza border in a video that has been widely shared "deserves a medal".

Earlier two Israeli right-wing ministers defended the soldiers after the video appearing to show them shoot a Palestinian and rejoice in it spread widely on social media and news sites.

The video comes at a highly sensitive time for Israel's military, which has faced mounting criticism over its use of live fire on the Gaza Strip border, where 31 Palestinians have been killed since late March as mass protests have led to clashes.

The shooting in the video appears to take place along Gaza's border with Israel.

Voices can be heard discussing opening fire on what seems to be Palestinians posing no immediate threat near the fence.

A shooter then appears to open fire on one, knocking the person to the ground.

"Wow. What a video! Yes! That son of a bitch," one of the voices behind the camera says in Hebrew.

It was not possible to determine whether the person shot in the video died.
