Israeli Defense Minister Avigdor Liberman backs ratifying a law allowing the execution of Palestinian detainees involved in killing or injuring Israelis, Israel's Channel 2 reported Wednesday.

This is not the first time for Liberman to raise this issue, the channel said, expecting Prime Minister Benjamin Netanyahu to give a push for such law.

Liberman's proposal came in response to Tuesday's attack at the entrance of a settlement, north of the occupied Jerusalem which left behind three Israelis killed.
