A second Oscar nominee has been denied entry to the United States.

Khaled Khatib, a 21-year-old Syrian cinematographer, was banned at the last minute from travelling to Los Angeles for Sunday’s Academy Awards.

His film, “The White Helmets”, had been nominated for an award in the Documentary (Short Subject) category. It tells the story of the country’s brutal civil war.

He had been due to fly to Los Angeles on Turkish airlines, but was refused permission to travel to the US because of “derogatory information” about him.

Syria was one of the countries named in Donald Trump’s immigration ban. But with the executive order being overturned by the courts, he had expected to be allowed to attend the Oscars.

The Department of Homeland Security declined to explain why the cinematographer had been refused entry.

The ban comes within weeks of an Iranian film director being refused permission to travel to the US.
