US ambassador to Israel Dan Shapiro has severely slammed Tel Aviv's authorities�for unjustly treating Palestinians, saying Prime Minister Benjamin Netanyahu applies separate �standards� of justice for Israelis and Palestinians.

�Too many attacks on Palestinians lack a vigorous investigation or response by Israeli authorities; too much vigilantism goes unchecked; and at times there seem to be two standards of adherence to the rule of law: one for Israelis and another for Palestinians,� Shapiro said at the Institute for National Security Studies (INSS) conference in Tel Aviv on Monday.

Shapiro also raised �questions about Israel�s long-term intentions� in the occupied West Bank, saying the US administration is �concerned and perplexed� by Tel Aviv�s settlement policy in the area.

�This government and previous Israeli governments have repeatedly expressed support for a negotiated settlement that would involve mutual recognition and separation,� he said. �Yet separation will become more and more difficult� if Israel continues its settlement activities.

The prime minister's office rejected Shapiro's unprecedented criticism, calling his remarks �unacceptable and wrong."

"Israel enforces the law on Israelis and Palestinians. The onus for the stalemate in the diplomatic process is [on] the Palestinian Authority, which continues to incite and refuses negotiations," it said.

In December, Israel's ministry of military affairs added a compound in the West Bank to the jurisdiction of the Gush Etzion regional council, a grouping of 20 settlements with a population of more than 20,000.

The plan will stretch Israel�s illegal settlements to the proximity of a volatile Palestinian refugee camp, raising the prospect of more clashes.

On January 8, US State Department Spokesman John Kirby slammed Israel for the plan, saying �continued settlement activity and expansion� will make it difficult to achieve a so-called �two-state solution.�

The continued expansion of Israeli settlements in occupied Palestine has created a major obstacle for the efforts to establish peace in the Middle East.

The United Nations and most countries regard the Israeli settlements as illegal because the territories were captured by Israel in a war in 1967 and are hence subject to the Geneva Conventions, which forbids construction on occupied lands.

Shapiro's remarks were made on a�day that an Israeli settler in a car ran over two Palestinian youths, riding on a motorbike, in an area near Salfeet city, killing one and injuring the other.

Late in 2015,�Israeli troopers shot and killed a young Palestinian woman after she allegedly tried�to stab soldiers at a checkpoint in the West Bank village of�Beit Einun,�five kilometers northeast of�al-Khalil (Hebron).

Since October 2015, at least 162 Palestinians and over two dozen Israelis have been killed amid tensions that rose after the Israeli regime imposed restrictions in August on the entry of Palestinian worshipers into the al-Aqsa Mosque compound in East al-Quds.
