The wave of protests over a film made in the United States that mocks the Prophet Mohammed has spread to the United Kingdom.

Muslims have marched in London as violent demonstrations continue to rage across the Middle East.

After the call to prayer at the Regent's Park mosque, about 200 people joined a protest march from the mosque to the US Embassy.

They held placards reading "America is the enemy of Islam and Muslims", and "Islam will dominate the world".

"Do not remain silent while they insult your messenger," the protest leader told the crowd.

The protest remained peaceful, but demonstrators set fire to a US and an Israeli flag.

Saiful Islam, a spokesman from Defenders of the Prophet, expects more protests in the UK and Europe.

"We should all be united in coming out to condemn the actions of these people," he told Saturday AM.

He says the violence - including the killing of the US ambassador to Libya - could have been seen coming.

"The thing with these killings and what is happening, obviously this was going to be expected," he said.

"Obviously when you do something like this, it's going to ignite and it's going to cause violence.

"I'm not surprised at all, I'm expecting obviously more carnage and more violence, and it's going to escalate."

Sorry, this video has expired Dr Anne Aly, an expert on Islam and terrorism, discusses the protests

The low-budget movie which sparked the protests, Innocence of Muslims, ridicules the Prophet Mohammed and belittles the religion he founded.

It touches on themes of paedophilia and homosexuality, while showing the Prophet sleeping with women, talking about killing children and referring to a donkey as "the first Muslim animal".

One protester in London says the movie shows ignorance about Islam.

"If you think of it, these people who have obviously taken part in this trailer of a movie have no idea of our Prophet and how much we actually love our Prophet," the protester said.

"They've taken it to a whole new level, and you're definitely going to see protests all across the world, not just across Europe."

But other Muslims in London told Saturday AM the violent protests go too far, and that words should only be fought with words.

"To be quite honest, it's quite characteristic of this organisation to convene whenever a reality like this occurs," one bystander said.

"I mean, it's happened all the time."

Another bystander condemned protesters for attacking embassies.

"We are losing support, and we are not giving the true idea of a true Muslim. A true Muslim should be civilised," the bystander said.
