LOS ANGELES (AP) — Immigration officials briefly detained the Palestinian director of the Oscar-nominated documentary "5 Broken Cameras" on his way into town for Sunday's Academy Awards.

Emad Burnat says that when he arrived at Los Angeles International Airport from Turkey with his wife and 8-year-old son late Tuesday, he was told he didn't have the proper proof that he was a nominee. After about an hour of questioning, they were allowed to enter the country.

Burnat had just been in the United States two weeks earlier doing interviews alongside his co-director, Israeli activist Guy Davidi, including some with The Associated Press.

Immigration officials did not respond to requests for comment.

"5 Broken Cameras" features footage Burnat shot in his occupied West Bank village, from everyday activities with his family to protests and shootings.
