U.S. President Donald Trump said Thursday that it's time for the United States to recognize Israel's control over the disputed Golan Heights, an announcement that signals a shift in U.S. policy and comes ahead of the Israeli prime minister's planned visit next week to the White House.

The administration has been considering recognizing Israel's sovereignty over the Golan, which Israel captured from Syria in the 1967 Arab-Israeli war.

Last week, in its annual human rights report, the State Department dropped the phrase "Israeli-occupied" from the Golan Heights section, instead calling it "Israeli-controlled."

Trump made his declaration in a tweet.

After 52 years it is time for the United States to fully recognize Israel’s Sovereignty over the Golan Heights, which is of critical strategic and security importance to the State of Israel and Regional Stability! —@realDonaldTrump

Trump's announcement came as U.S. Secretary of State Mike Pompeo is in Jerusalem, lauding warm ties with Israel and promising to step up pressure on Iran. Pompeo was asked about the issue, but declined to answer.

Israeli Prime Minister Benjamin Netanyahu faces an election on April 9 and has been pressing for the United States to recognize Israel's claim to sovereignty over the Golan Heights.

Trump remains popular in Israel, and his advisers have been developing a Middle East peace proposal for release sometime after the Israeli elections. Netanyahu tweeted his gratitude.

At a time when Iran seeks to use Syria as a platform to destroy Israel, President Trump boldly recognizes Israeli sovereignty over the Golan Heights. Thank you President Trump! <a href="https://twitter.com/realDonaldTrump?ref_src=twsrc%5Etfw">@realDonaldTrump</a> —@netanyahu

Israel captured much of the Golan from Syria in a 1967 war and annexed it, a move not endorsed internationally. Netanyahu raised the possibility of U.S. recognition in his first White House meeting with Trump in February 2017.

Richard Haass, a former senior State Department official who is president of the Council on Foreign Relations, said in a tweet he strongly disagreed with Trump's Golan decision.

He said the move violates UN Security Council resolution 242, "which rules out acquiring territory by war and serves Israel as it says all states have right 2 live in peace."

A Golan Heights force was set up after the 1973 Arab-Israeli war to monitor the ceasefire. Much of the world, including Canada, recognizes the Golan Heights as occupied territory.

Canada ended a 32-year peacekeeping mission in the Golan Heights in 2006.
