US President Barack Obama has described as "hateful" and "offensive" the claim by Iran's President Mahmoud Ahmadinejad that most people believe the US government was behind the 9/11 attacks. Mr Obama was speaking exclusively to BBC Persian television, which broadcasts to Iran and Afghanistan.

"This is not a matter of us choosing to impose punishment on the Iranians," he told the BBC. "This is a matter of the Iranian government ultimately betraying the interests of its own people by isolating it further." And he pointed out that countries such as Russia and China had also backed the UN sanctions. "Most of these sanctions are targeted at the regime, at its military, and we think that over time, hopefully, there's enough reflection within the Iranian government, that they say to themselves, you know, 'This is not the best course for our people. This is not the best course for Iran.'"

the Iranians "seem to be talking about talks about talks".

As blogging becomes more popular, Saudi Arabian authorities are starting to treat it with the same caution and restriction applied to traditional media in the country. Of course this has gotten many bloggers upset, and people have taken to Twitter to protest, with the hashtag #haza3 which refers to the Ministry official’s last name. Public protesting is illegal in Saudi Arabia.

The demonstrators on Tuesday did the unthinkable: publicly burning the pictures of Gamal Mubarak, son of the president, who is suspected of being groomed to succeed his father. The issue is so sensitive that security forces rushed to confiscate footage shot by the cameras of Al Jazeera and the BBC. Nevertheless, the news spread like wildfire and some still photographs made their way to cyberspace.

the old tactics of muzzling public opinion may not be as efficient anymore

A researcher at the London-based International Centre for the Study of Radicalisation told the BBC that the number of radical websites was now far higher than the figure given by Interpol. "It's well into the thousands in English alone,"

it was not the opposition of "fundamentalists" that kept rai music (not just Khaled's) off of Algerian state radio. It was rather the Algerian (secular) regime's cultural policies. The state promoted classical Arabic culture and language and denied Algeria's multi-cultural nature. Expressive culture in Arabic dialect or Berber was therefore mostly excluded from the state-controlled media. Rai is sung in the distinctive colloquial Arabic of Wahran, which is not only very different from "classical" or literary Arabic but is also full of borrowings from Spanish, French and Berber. This official national-cultural politics, which was particularly severe during the regime of Houari Boumediene (1965-1978), began to loosen during Chadly Benjadid's regime (1979-1992). In his 1998 autobiography, "Derrière la sourire," Khaled recounts how he managed to break the official embargo in the early 1980s. He was invited to appear on a television show in Algiers, which he knew couldn't be censored because it was to be broadcast live. Khaled was warned ahead of time: no vulgarities, no sex. So he sang three songs: the first, about the Prophet Muhammad; the second, a "poetic" song, one that was artistically acceptable; and the third, about alcohol and women.

Khaled, and other rai stars, came to play at this festival due to the efforts of the "liberal" wing of the Algerian regime -- and particularly to Lieutenant-Colonel Hosni Snoussi, director of the state-supported arts and culture organization, Office Riadh el Feth in Algiers, who had taken Cheb Khaled under his wing. The regime's liberal wing became interested in promoting rai in the wake of a spate of unrest that erupted during the early 1980s. Most notably, the 1980 riots in Tizi Ouzou, Kabylia (the "Berber Spring"); the 1985 riots in Algiers, which broke out following rumors that housing being built for the poor would be allocated to state bureaucrats; and the 1986 student riots in Constantine that resulted in the deaths of four protesters and spread to other cities. Young Algerians played a leading role in all these protests. The liberal wing of the regime determined that, to deter further unrest, the state should focus on promoting the interests of youth and on developing the market economy. Rai was very popular with Algerian youth, and so the "liberals" determined that promoting it was to be an important element of these reform efforts. It was changes in state policy toward rai, pushed by Snoussi, that got Khaled and other rai stars onto the stage in Algiers in 1985.

The French government had a stake in trying to control and channel the energies of the rai scene.

"The internet has revolutionised political life in Egypt," comments Mustafa Kamel al-Sayyid, a politics professor at the American University in Cairo. "It's a tool enabling opposition groups, particularly those who are subject to suppression by the government, to communicate with their members and co-ordinate activities."

with only 13 million internet users in a population of 80 million, he worries the medium has its limits. "The rest of the population still isn't reached," Mr Maher points out. "We need to find ways to reach the street. The ruling party is allowing internet use while it oppresses any opposition presence in the streets because it doesn't see the internet as a real threat."
