More than 400 prisoners, including members of the Taliban, have escaped a jail in Afghanistan after insurgents tunnelled in to free them.

Kandahar is known as the birthplace of the Taliban 
The majority of the 476 prisoners who fled the 1,200-inmate Sarposa Prison were Taliban militants, according to prison supervisor Ghulam Dastagi Mayar.
It is the second major jailbreak from the prison in Kandahar province, the spiritual birthplace of the Taliban, in three years.
It is supposed to be the most secure jail in the country.
The Taliban, known for exaggerating its successes, claimed that 541 prisoners, including many commanders, had escaped through an extensive tunnel which took months to create.
A Taliban statement said: "Mujahideen started digging a 320-metre tunnel to the prison from the south side, which was completed after a five-month period, by-passing enemy check posts and (the) Kandahar-Kabul main highway leading directly to the political prison."
The provincial governor's spokesperson Zalmay Ayoubi confirmed the jailbreak, saying: "We have the report that hundreds of Taliban managed to escape from the prison."
Waheed Mujhda, a Kabul-based expert on the Taliban, said it would have been impossible to dig the tunnel and free hundreds without collaboration with the guards.
"It is either a case of the jailers being financially motivated and being bribed or a case of them being politically motivated," he said.


The security breach comes just months before the start of a transfer of responsibilities from foreign to Afghan forces as Nato troops begin their withdrawal from the country.
Afghan forces will take over from foreign troops in stages and should be in charge of the whole country by 2014.
In 2008, Taliban insurgents blew open the gate of the prison, allowing up to 1,000 prisoners to escape.
Days later, Taliban fighters took many villages close to Kandahar, sparking fierce fighting with the Afghan army.
The Taliban said the tunnel was completed late on Sunday night and hundreds of insurgents escaped over a four-and-a-half hour period.
"Mujahideen later on sent vehicles to the inmates who were led away to secure destinations," said the statement.
The Nato-led International Security Assistance Force (ISAF) said international troops were on standby to provide assistance.
"We have no involvement at this point," said ISAF spokesman Major Michael Johnson in Kabul.
"If we're asked to assist in any capacity, we would certainly be standing by to do that."
