UK imposes sanctions on art collector accused of financing Hezbollah

Nazem Ahmad, who has owned works by Picasso and Warhol, suspected of laundering money for militant group

A high-profile art collector has been put on a Treasury sanctions list over claims he uses his collection, which has included masterpieces by Pablo Picasso, Antony Gormley and Andy Warhol, to launder money for the Lebanese militant group Hezbollah through the UK.

Nazem Ahmad, a diamond and art dealer who once posed in his Beirut penthouse for a glossy magazine and featured in a piece about the world's most beautiful homes and the fascinating people who live in them", has been targeted under new counter-terrorism powers.
