Trump on Wednesday recognized Jerusalem as Israel's capital and announced plans to relocate the U.S. Embassy there.

"I have determined that it is time to officially recognize Jerusalem as the capital of Israel," Trump said during a speech in the Diplomatic Reception Room of the White House.

Trump has vowed to broker a historic peace accord between Israel and Palestine. On Wednesday, he said he will try to resolve the decades-old conflict his way, arguing that past approaches, such as delaying the recognition, have not worked.

“It would be folly to assume that repeating the exact same formula would now produce a different or better result,” he said, calling his announcement “a long-overdue step to advance the peace process and work towards a lasting agreement.”

Arab and European leaders warned that formally recognizing Jerusalem as Israel's capital would push Middle East peace talks further off track.
