Mr. Barghouti was supposed to speak at a series of events in the United States organized by the Arab American Institute in Washington, including at panels at Harvard University and an event with New York University. He was also planning to attend his daughter’s wedding in Texas.
Mr. Barghouti, a permanent resident of Israel, was stopped at Israel’s international airport when he tried to board a flight to Washington via Frankfurt, and airline staff told him only that the American Consulate in Tel Aviv had been directed to stop him from traveling. He said he was told it was an immigration matter but was given no further explanation.
