British commentator Sami Hamdi was detained on Sunday by federal immigration officers during a speaking tour in the United States, in what a Muslim advocacy group said was retaliation for his criticism of Israel.

British commentator Sami Hamdi has been detained by US immigration, who have revoked his visa and banned him from completing his speaking tour, a Homeland Security official said.

Ten days after the October 7 Hamas attacks, which claimed the lives of 1,200 Israelis, Hamdi was filmed encouraging people to 'celebrate the victory' of the terrorist organization.
