Anger and protests, in the Arab world have spread today to Yemen, where massive crowds have stormed the grounds of the American embassy in the Yemeni capital, Sanaa. Protesting over a US based alleged anti-Islam film.

Hundreds of Yemeni demonstrators attacked the U.S. embassy in Sanaa, clambering over the high walls to gain access to the US Embassy with many reported injuries. Police fired shots into the crowd to gain control, but the sheer force of numbers overcame them and once inside the compound, the protestors set fire to vehicles.

There have also been clashes at the US Embassy in the Egyptian capital, Cairo. Hundreds of Muslims line the street, chanting pro Islam slogans armed with sticks, metal bars and smoke bombs. Which has prompted President Mursi to release a statement saying "I condemn and oppose all who... insult our prophet. But it is our duty to protect our guests and visitors from abroad."

The anger over the film has also spread to Bangladesh as Muslim men march on the streets in protest ,saying that the film maker must be arrested immediately punished.

These protests follow the deaths of US Ambassador Christopher Stevens and four other US Embassy officials at the US Consulate in Benghazi on Tuesday. At first, the attack in Benghazi was believed to be a protest 'against' the alleged anti-Muslim film, but now the US believes the attack was pre meditated and that a militant Jihadist group may have carried out the attack. In response to the rising tensions and attacks, US Security has been increased at US embassies and consulates around the world. And there is great concern that these attacks and protests may spread to the wider Arab world.
