Ai Weiwei covers Berlin landmark in used life jackets for new artwork
Chinese artist Ai Weiwei has used thousands of used life jackets from refugees in his latest art installation in Berlin.
Ai Weiwei wrapped 14,000 bright orange vests around the pillars of the city's Konzerthaus to highlight the risk refugees are taking every day to reach Europe by sea from Turkey.
Authorities on the Greek island of Lesbos gave the artist the life vests.
