Protesters attacking the US embassy in Yemen
BBC
Protesters angered by a film made in the US and mocking Islam have attacked Western embassies in Tunisia and Sudan.
Protesters in Khartoum entered the US compound, while the German and UK embassies were also attacked. The US compound in Tunis was also breached by protesters, who started a fire in the car park as police fired shots, reports the BBC.
There were further clashes in Yemen and Egypt. One person in Lebanon has died.
Protests began on Tuesday against the film, which was made in the US.
However, the film - clips of which were dubbed into Arabic and distributed online - has no link to either Germany or the UK.
It depicts the Prophet Muhammad as a womaniser and leader of a group of men who enjoy killing.
The film's exact origin and the motivation behind its production remain a mystery.
In Tunisia, hundreds of protesters entered the embassy compound and a large fire is alight in the car park.
Police have fired shots, but it is not clear whether these are rubber bullets or live rounds.
Demonstrators have raised a black flag bearing the Islamic proclamation of faith: "There is no god but Allah and Muhammad is his messenger."
A spokesperson for the UK Foreign Office confirmed to the BBC that a demonstration was taking place outside the embassy in Khartoum, and said Sudanese police were at the scene.
However, the spokesperson could not say whether protesters had entered the embassy, or whether the demonstration was about the anti-Islam film.
The German embassy in Khartoum was set partially alight. Demonstrators tore down the German flag and hoisted an Islamic banner in its place.
The German foreign ministry confirmed all its staff in Khartoum were safe.
In Cairo, police firing tear gas pushed about 500 protesters back from the US embassy. The streets nearby have been blocked with barbed wire, concrete and police vehicles.
Islamist groups and others had called for a peaceful "million-man march" in the city, but a number withdrew those calls on Friday.
The Muslim Brotherhood of Egyptian President Mohammed Mursi said it would organise marches and sit-ins in front of mosques - but none outside the US embassy in Cairo.
After talks with Italian leaders in Rome, Mursi reiterated his government's determination to protect foreign diplomats on its soil. He also condemned the film as unacceptable.

The protests against the film began on Tuesday in Cairo.
They spread to the Libyan city of Benghazi, where demonstrators stormed the US consulate, killing the ambassador and three other Americans.
The US has said it is stepping up security at its diplomatic missions around the world in the wake of the attack.
The BBC has been told that the US consulate in Benghazi was not given the standard security contract offered to most US diplomatic missions in the Middle East.
The allegation came from Western private military contractors.
The US state department has refused to comment.
