Afghan insurgents are believed to be holding at least six Turkish engineers after their helicopter was forced down by bad weather in Taliban controlled eastern Afghanistan.
The aircraft, operated by charter firm Khorasan Cargo, made an emergency landing in Logar province on Sunday afternoon.
The company says it spoke to the craft’s two pilots briefly but nothing has been heard since they landed.
Khorasan flies Russian Mi-8 and Mi-17 helicopters as well as fixed-wing aircraft in Afghanistan.
