Fresh protests in Pakistan, Afghanistan and Indonesia have erupted over an anti-Islam film made in the US, which many say mocks the Prophet Mohammed.
In Pakistan, hundreds of protesters demonstrating against the film, torched a press club and a government building in the northwestern town of Wari.
One demonstrator has been killed and several others wounded.
In Afghanistan, protests turned violent outside a US military base in Kabul, where about 800 protesters burned cars and threw rocks at Camp Phoenix.
Many in the crowd shouted "death to America!" and "death to those people who have made a film and insulted our Prophet."
Police fired into the air to hold back the crowd and to prevent it from pushing toward government buildings downtown.
More than 40 police officers were slightly injured, most of them hit by rocks.
In Indonesia, hundreds clashed with police outside the US Embassy in Jakarta, hurling rocks and firebombs and setting tyres alight.
It was the first violence seen in the world's most populous Muslim country since international outrage over the film exploded last week.
Demonstrations started on Tuesday in Egypt when the film trailer came to light.
