Afghan helicopter crash kills six
Six Nato soldiers have been killed in a helicopter crash in Afghanistan, the worst crash since 30 soldiers died last August.
A Nato statement said the helicopter came down in the south of the country, cited by the BBC.
Nato said no insurgent activity had been reported in the area at the time and the cause of the crash is being investigated. No further details of the crash would be released until the families of those on board had been informed, Nato said.
Isaf has not disclosed the nationalities of those killed.
The crash happened on the same day at least seven civilians died in a suicide attack at an airport used by international forces in the southern Afghan city of Kandahar.
The attacker, driving a car, detonated explosives close to a gate at the perimeter of the airport. Afghan officials said the victims included two children.
The Taliban have said they were behind the attack, which analysts say shows Kandahar's fragile security situation.
In August 2011, 30 soldiers, including 22 US Navy Seal commandos, died in a helicopter crash in the east of Afghanistan.
They were aboard a Chinook helicopter that went down in a district of Wardak province, west of Kabul. Officials, witnesses and the Taliban have said it was shot down by insurgents during a combat mission.
