the beginning of the show, the latest in the middle east. Violent anti-american protests overnight in egypt. Abc's lama hasan is on the front lines of the demonstrations in cairo right now. Lama, good morning to you. Reporter: Good morning, elizabeth. Well, this is a city bracing itself for a huge amount of outpouring of anger. The streets of cairo are once again a war zone. We're overlooking tahrir square, just down the street from where we are is the u.S. Embassy. We can see the security forces who are meant to be guarding the embassy, firing tear gas at the protesters, trying to push them back. But the crowd is going nowhere. They are digging in and getting ready for a fight. Many thousands anticipating to take part in a million man march. Protests by the muslim brotherhood. Police in riot gear launching tear gas canisters into the sea of violent protesters. It's now the fourth day of anti-american demonstrations, fueled by an amateur film called "innocence of muslims." Many here say the movie is blasphemous, denigrating the prophet muhammad. My message is to stop. Stop disrespecting us. Reporter: Back in the u.S., police and reporters surrounded the california home of the man who allegedly produced the controversial film. Police tell abc news, nakoula basseley nakoula, a 55-year-old egyptian christian, used the assumed name sam bacile to make and promote the movie. Nakoula told police he wrote the movie while serving time in federal prison last year on charges of bank fraud. This morning, after seeing the violence his film has sparked, he tells abc news, he now fears for his life. Following an investigation into the killings at the u.S. Embassy in benghazi, there are reports of four people have been arrested. The libyan prime minister has said, expect more arrests.
