Protests took place in Afghanistan, Indonesia, the Philippines and Yemen in the latest eruptions of anger over the low-budget trailer aired on YouTube that has now led to the deaths of at least 19 people.

The movie entitled Innocence of Muslims, believed to have been produced by a small group of extremist Christians, has sparked a week of furious protests outside US embassies and other US symbols in at least 20 countries.

   Two protesters died in Pakistan on Monday as the violent backlash against the anti-Islamic film spread across the region and angry demonstrators clashed with police, hurling stones and shouting "Death to America."  

Thousands of students burned US flags and chanted anti-US slogans in the northwest city of Peshawar, north of Pakistan, where Osama bin Laden kept a home during the 1980s jihad against the Soviet Union's troops in adjacent Afghanistan.

In the nearby district of Upper Dir, next to a former Taliban stronghold crushed in 2009, a protester was killed and two others wounded in a shootout with police.

The crowd of around 800 people set fire to a magistrate's house and the local press club.

In Karachi, Pakistan's biggest city, another demonstrator died after being shot in the head during clashes with police near the US consulate on Sunday.

In neighboring Afghanistan, protests turned violent for the first time when more than 1,000 Afghans protested in Kabul, setting police cars and commercial storage containers ablaze, police told AFP.

Between 40 and 50 policemen were "very slightly wounded" by stone throwers and members of the crowd waving sticks, said Kabul police chief Mohammad Ayoub Salangi, who added that he had also been grazed by a stone.

A police official, who gave his name only as Hafiz, said protesters also threw stones at Camp Phoenix, a US-run military base in the capital, but were later driven back.

Google has barred access to the video in Egypt, India, Indonesia, Libya and Malaysia, while the government has restricted access to Google-owned YouTube in Afghanistan.

In Jakarta, protesters hurled petrol bombs and clashed with Indonesian police outside the US embassy shouting "America, America go to hell," as demonstrations in the world's most populous Muslim nation turned violent.

Police were seen kicking or dragging away some of the protesters, while one policeman was taken away in an ambulance with his face bleeding.

Many of the protesters were supporters of hardline Islamic groups and were dressed in identical white Muslim garb, an AFP reporter saw.

The capital's police chief Untung Rajab said 11 policemen and a protester were injured and taken to hospital, and that four protesters were arrested.

The fresh violence came one day after the head of the Shiite Muslim movement Hezbollah, blacklisted in the US as a terrorist group, called for a week of protests.

Hassan Nasrallah described the film as "the worst attack ever on Islam," worse than The Satanic Verses by British author Salman Rushdie, who has been under an Iranian fatwa calling for his murder since 1989.

"The whole world needs to see your anger on your faces, in your fists and your shouts," he said in a televised speech broadcast.
