US President Barack Obama has said that the US does not consider Egypt to be an ally nor an enemy.

His comments came after clashes and demonstrations outside US consulates across the Middle East, which spread after a movie that was deemed blasphemous by some was made in the US.

"I don't think we would consider them an ally, but we don't consider them an enemy. They are a new government that is trying to find its way," Mr Obama said in a television interview with Telemundo.

He said that Egypt's government has "said the right thing and taken the right steps" but at the same time it has responded to other events in ways that "may not be aligned with our interests".

"Certainly in this situation, what we're going to expect is that (the Egyptian government is) responsive to our insistence that our embassy is protected, our personnel is protected, and if they take actions that they’re not taking those responsibilities, as all countries do where we have embassies, I think that’s going to be a real big problem.”

President Mohammad Mursi has also appealed for calm and condemned those who insulted Mohammad.

"I call on everyone to take that into consideration, to not violate Egyptian law... to not assault embassies."

"I condemn and oppose all who... insult our prophet. [But] it is our duty to protect our guests and visitors from abroad," he said in a statement.

However the Muslim Brotherhood has been embarrassed after a gaffe saw inconsistencies between its English and Arabic Twitter accounts.

The Brotherhood tweeted in English that it was relieved no embassy staff were ‘harmed’ during the protests and that they hope that ‘US-Eg relations will sustain the turbulence, while its Arabic twitter account called for more protests.”

The US Embassy in Cairo said in a reply that they read the Arabic tweets too.

“..By the way, have you checked out your own Arabic feeds? I hope you know we read those too” the embassy tweeted in response.
