UN High Commissioner for Human Rights Zeid Ra'ad Al Hussein said Friday Israel's cancellation of entry permits for Palestinians may amount to collective punishment, Al Arabiya reported.

The Israeli occupation on Thursday revoked permits for 83,000 Palestinians to visit Israel and said it would send hundreds more troops to the occupied West Bank after a Palestinian gun attack that killed four Israelis in Tel Aviv.

Al Hussein condemned the attack but he was deeply concerned about the revoking of permits "which may amount to prohibited collective punishment and will only increase the sense of injustice and frustration felt by Palestinians," spokeswoman Ravina Shamdasani told a news briefing.
