Chinese boats entered disputed waters between China and Japan on Thursday, as the row over a set of islands claimed by both nations continues to worsen.

Six ships were sent by China to the contested area, with the Chinese foreign ministry stating,

"These law enforcement and patrol activities are aimed to demonstrate China's jurisdiction over the Diaoyu Islands and its affiliated islets and ensure the country's maritime interests."

The protests over the obscure movie about Mohammad have escalated around the world.

Three protestors died after thousands of people attacked the US embassy in Khartoum, according to Sudanese state radio.

The mob initially attacked the German embassy and set fire to it, causing severe damage.

The British embassy nearby also saw protests but was not damaged. Germany and the UK have no link to the film.

"I condemn in the strongest possible terms today's attack and call on the Sudanese authorities to ensure that those involved are brought to justice," said UK Foreign Secretary William Hague.

Over a dozen peaceful reform activists have been arrested in Jordan over the past week says Human Rights Watch (HRW).

The wave of arrests indicates a reinforcement of intolerance towards calls for political demands in the kingdom.

At least seventeen activists and peaceful protesters have been arrested across the country and remain in detention under terrorism charges.

Senior Middle East researcher at Human Rights Watch, Christoph Wilcke said:

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.

Human Rights Watch (HRW) has found at least four politicians responsible for violent clashes in the Tana River County in August and early September.

A Kenyan MP, Dhadho Godhana was arrested on Wednesday in connection with the violence which is reported to have claimed the lives of at least 110 people and left 6000 displaced.

HRW research implicates at least three other politicians in organising the violence, as well as pointing out the failure of police to take preventative measures despite warnings.

Cambodia’s long running Khmer Rouge war crimes court has ordered the release of the “first lady” who has been declared unfit to stand trial.

The UN backed court ruled that there was no prospect that Ieng Thirith, who is 80 years old, could stand trial due to a degenerative illness that she suffers from.

Ieng Thirith, stands accused of war crimes, genocide and crimes against humanity for her role in the Khmer Regime which, some estimates suggest, resulted in the death of over 2 million people.

Some 1.5 million people took part in Catalonia's annual independence rally in Barcelona on Saturday, the BBC reports, citing police.

Catalonia has a population of 7.6 million.

The size of the turnout for the rally, which is held annually on 11 September to mark the Siege of Barcelona 300 years ago, forced organisers to change its route.

The US Ambassador to Libya has been killed during an attack by protestors on the US embassy in Benghazi, according to government officials.

Al-Jazeera reported that the ambassador came under rocket fire whilst in a car and died from smoke inhalation with three other staff of the embassy.

An armed mob attacked the compound on Tuesday after a film critical of Islam was made in the US and released on YouTube.

Wanis al-Sharif, the Libyan deputy interior minister, confirmed the deaths to the AFP news agency.

Mustafa Abu Shagur, the Libyan deputy prime minister, condemned the "cowardly act of attacking the US consulate and the killing of [the ambassador] and the other diplomats".

The president of Libya’s national assembly Mohammed Magarief has apologised for the killing of the US Ambassador Christopher Stevens, which has drawn widespread condemnation, including from the Muslim Brotherhood.

"We apologise to the United States, the people and to the whole world for what happened," he told a news conference broadcast live on Al Jazeera television.

US President Obama has praised the courage of the Ambassador and while condemning the attacks, noted that it was Libyans who carried the ambassador to a hospital.

"While the United States rejects efforts to denigrate the religious beliefs of others, we must all unequivocally oppose the kind of senseless violence that took the lives of these public servants," Obama said in a White House statement.
