In an unprecedented move, Israel's ambassador to the United Nations has been elected to head a permanent committee at the United Nations.
After months of diplomatic efforts, Danny Danon was elected chair of a General Assembly committee handling legal issues on Monday.
It is the first time an Israeli representative will head a permanent UN group. Mr Danon's election came despite strong attempts by Arab states to stop his nomination.
He said: "This is a historic achievement. We broke the glass ceiling."
Mr Danon received backing from the United States and a number of western European nations.
The committee he will head is in charge of the UN's activities regarding international law, and co-ordinates its fight against terrorism.
He said: "Israel is a world leader in international law and in fighting terrorism. We are pleased to have the opportunity to share our knowledge with the countries of the world."
The World Jewish Congress President, Ronald S Lauder, said Mr Danon's appointment was "a significant victory for Israel and a glimmer of hope".
