The Israeli military 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.
UN High Commissioner for Human Rights Zeid Ra'ad Al Hussein condemns the attack but is 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.
This comes after US Republican presidential candidate Donald Trump on Thursday condemned a Palestinian gun attack in Tel Aviv in which four Israelis were killed, and criticised Hamas' praise of the attackers.

"I condemn, in the strongest possible terms, the outrageous terrorist shootings that took the lives of at least four innocent civilians and wounded at least twenty others in Tel Aviv yesterday," Trump said in a Facebook post.
Trump said that while the investigation into the attack is ongoing, it was "despicable" that Palestinian militant group Hamas had called the attackers heroes.
"The American people stand strong with the people of Israel, who have suffered far too long from terrorism. Israel's security is a matter of paramount importance to me and the American people," he said.
The US State Department urged the Israeli military not to punish innocent Palestinians.
"We understand the Israeli government's desire to protect its citizens ... and we strongly support that right, but we would hope that any measures it takes are designed to also take into consideration the impact on Palestinian citizens that are trying to go about their daily lives," State Department spokesman Mark Toner told a news briefing.
