A 19-year-old British woman has been detained in Tbilisi accused of carrying 14kg of cannabis into ex-Soviet republic Georgia.

The woman - identified as B.K. - could face 20 years jail or even life imprisonment, said the Georgian Ministry of Internal Affairs.

A video shows the handcuffed woman after she was held at Tbilisi Airport.

'During the inspection, 34 hermetically sealed packages containing marijuana were found in the passenger's bag, as well as 20 packages of hashish,' said a local report.

Footage showed the drugs allegedly carried by the woman.
