Charlie Hebdo attack: Print run for new issue expanded
Millions more copies of French weekly Charlie Hebdo are being printed after the first run sold out in hours.
The normal print run of 60,000 was extended to five million - a week after Islamist gunmen murdered 12 people at the magazine's offices and five others in subsequent attacks in Paris.
The "survivors' issue" has angered some Muslims by depicting the Prophet Muhammad on its cover.
A video purportedly from al-Qaeda in Yemen said it planned the Hebdo attack.
US state department spokeswoman Marie Harf said they believed the video was authentic but could not determine if its claims were true.
The group, AQAP, had previously welcomed the attack, without acknowledging any role in the operation.
The gunmen are said to have used earlier publication of images of the Prophet as justification for their attack on the magazine.
Charlie Hebdo's latest cover shows a cartoon depicting the Prophet Muhammad weeping while holding a sign saying "I am Charlie", and below the headline "All is forgiven".
"I am Charlie" emerged as a message of support for the magazine following the attack on 7 January, which left eight journalists, including its editor, dead in addition to four others.
In a separate attack in Paris two days later, an Islamist gunman killed four Jewish men and took hostages at a kosher shop.
The same attacker is believed to have shot a policewoman the day before.
'Charlie is alive'
Normally Charlie Hebdo prints 60,000 copies but the planned run increased steadily this week - from one million to three million to five million.
The "survivors' issue", as the magazine calls it, is available in six languages including English, Arabic and Turkish. Proceeds are going to victims' families.
President Francois Hollande has insisted the magazine and its values will continue.
"Charlie Hebdo is alive and will live on," he said. "You can assassinate men and women but you will never kill their ideas."
Charlie Hebdo's decision to publish another cartoon of the Prophet drew threats from militant Islamist websites and criticism from the Islamic world.
The Islamic State (IS) militant group said it was "an extremely stupid act".
Meanwhile, a new video apparently from AQAP said the group had planned and financed the Charlie Hebdo attacks in "vengeance for the Prophet".
It said it was a "success" that the magazine shootings had "coincided" with the attacks by supermarket gunman Amedy Coulibaly.

The video purporting to come from AQAP does appear to be genuine but questions remain over just how closely AQAP was really involved in last week's Paris attacks. More than two years have elapsed since Said Kouachi, one of the three gunmen, is believed to have slipped out of Yemen after spending time there with al-Qaeda members, including the extremist preacher Anwar Al-Awlaki.
He is mentioned in the video in connection with the attack planning but Al-Awlaki was killed back in 2011 in a US drone strike so, again, that would be a long time to plan such a relatively simple but devastating attack.
It is also odd that AQAP have not issued any so-called "martyrdom videos", showing the perpetrators giving their justifications ahead of the raid.
These may still be to come but for now it seems the connection between the Paris attackers and AQAP is more one of inspiration, ideology and training rather than close direction and leadership.
Coulibaly had pledged allegiance to IS in a video message while the Charlie Hebdo attackers, Said and Cherif Kouachi, had said they were acting on behalf of AQAP.
Coulibaly had said they had co-ordinated the attacks but experts say it is highly unlikely IS and AQAP, rivals in the Middle East, would work together.
Meanwhile a lawyer for Said Kouachi's wife, Soumya, has told the BBC she had no idea he was an extremist. He said Kouachi had kissed his wife goodbye and told her he was visiting his brother, because he was unwell, just hours before the Charlie Hebdo attack.
"It's beyond her understanding, her world has fallen apart," the lawyer, Antoine Flasaquier, said.
Ban on distribution
The magazine's release comes after millions - including dozens of world leaders - took part in a unity rally in Paris on Sunday.
Outside France, the Washington Post, Germany's Frankfurter Allgemeine, Corriere della Sera in Italy and the UK's Guardian are among publications that have shown the latest cartoon.
The BBC has published the image in a previous story and in a statement said: "We have made the editorial judgment that the images are central to reporting the story."
Why people are buying the magazine
Catherine Boniface, Paris: "This issue is symbolic, it represents their persistence, they didn't yield in the face of terror."
Meanwhile, the interior minister of Senegal - whose president took part in the Paris march - has issued an order banning the distribution of the magazine, according to the national news agency.
Several hundred people attended the funeral on Wednesday of Michel Renaud, who was killed while visiting Charlie Hebdo's offices.
Ceremonies were held for seven other victims in France and Israel on Tuesday.
Meanwhile, controversial French comedian Dieudonne M'bala M'bala has been arrested for "defending terrorism" after he likened himself to gunman Amedy Coulibaly.
A judicial source quoted by AFP news agency said he was due to be released on Wednesday evening but would face trial at a later date.
Police are also investigating some 50 people suspected of "condoning terrorism" and 25 cases of people attacking or defacing Muslim places of worship.
