KABUL (Reuters) -- Protesters in Afghanistan, Lebanon, Pakistan and Indonesia burnt US flags and chanted "Death to America" on Monday in renewed demonstrations over a film mocking the Prophet Muhammad that has unleashed a wave of anti-Western sentiment in the Muslim and Arab world.

Thousands of Lebanese protesters chanting "Death to America, Death to Israel" marched through Beirut's Shiiite southern suburbs in protest against the film.

"America, hear us - don't insult our Prophet," chanted the marchers at the demonstration, called for by the leader of the Shiite Muslim group Hezbollah, Sayyed Hassan Nasrallah.

Indonesian police fired teargas and water cannon to disperse hundreds of demonstrators who massed outside the US Embassy in Jakarta, capital of the most populous Muslim nation.

In Karachi, Pakistan's commercial hub, protesters on motorcycles and in cars headed towards the US consulate, prompting police to shoot in the air and fire teargas.

Protesters threw rocks at the police and damaged one of their vehicles. Around 100 people roamed roads and alleys near the sprawling consulate.

In the city of Lahore, protesters threw rocks at police and burned an American flag near the US consulate. Police official Rai Tahir said six policemen and some protesters were hurt.

In Kabul, thousands of protesters took to the streets, setting fire to cars and shops and throwing stones at police.

"We will defend our prophet until we have blood across our bodies. We will not let anyone insult him," said one protester in the Afghan capital. "Americans will pay for their dishonor."

The demonstrations were the latest across the world provoked by a short film made with private funds in the United States that depicted the Prophet Muhammad as a fool and womanizer.

In a torrent of violence last week, the US ambassador to Libya and three other Americans were killed in an attack in Benghazi and US and other foreign embassies were stormed in several cities in Asia, Africa and the Middle East by enraged Muslims. At least nine other people have been killed.

The United States has sent ships, extra troops and special forces to protect its interests and citizens in the Middle East while a number of its embassies have evacuated staff and are on high alert for trouble.

The situation poses an unexpected foreign policy headache for US President Barack Obama as he campaigns for re-election in November, even though his administration has condemned the film as reprehensible and disgusting.

Despite efforts early in his tenure to improve relations with the Arab and Muslim world, he faces a number of problems including the continued US military involvement in Afghanistan, Iran's nuclear program, the Syrian civil war and the fall-out from the Arab Spring revolts.

US, Israel flags burned

The renewed protests on Monday dashed any hopes that the furor over the film might fade despite an appeal from the senior cleric in Saudi Arabia, home to Islam's holiest shrines, for calm over the weekend.

In the Kabul demonstration, protesters shouted "Death to America" and burned the flags of the United States and of Israel, a country reviled by many Muslims and Arabs because of the Palestinian issue.

Police Lieutenant-General Fahem Qayem put the number of demonstrators at between 3,000 and 4,000 but said police had the situation under control.

Embassies in central Kabul, including the US and British missions, were placed on lock-down and violence flared near fortified housing compounds for foreign workers.

Rallies also took place in London, Australia, Turkey and Pakistan on Sunday, showing the global scale of the outrage.

In other developments on Monday, Iran said it would hunt for those responsible for making the film.

"The government of the Islamic Republic of Iran condemns this inappropriate and offensive action," First Vice-President Mohammad Reza Rahimi said. "Certainly it will search for, track, and pursue this guilty person who has insulted 1.5 billion Muslims in the world."

Iranian officials have demanded that the United States apologize to Muslims for the film, saying it is only the latest in a series of Western insults aimed at Islam's holy figures.

The head of Lebanon's Iranian-allied Hezbollah, Sayyed Hassan Nasrallah, called for protests in Beirut this week and said the United States must be held accountable.

"All these developments are being orchestrated by US intelligence," he said.

The identity of those directly responsible for the film is still murky. Clips posted online since July have been attributed to a man named Sam Bacile, which two people connected with the film have said was probably an alias.

Nakoula Basseley Nakoula, 55, a Coptic Christian widely linked to the film in media reports, was questioned in California on Saturday by US authorities investigating possible violations of his probation for a bank fraud conviction.
