Rock band U2 are encouraging fans to don special masks during their current tour to highlight the plight of a political prisoner in Burma.

Masks of democratic party leader Aung San Suu Kyi's face are available for download from the U2 website.
The band has asked fans to wear the masks during their song Walk On to highlight the fact that Aung San Suu Kyi has spent most of the past two decades under house arrest.

A statement on the website says: “U2 believe the world must not be allowed to forget Aung San Suu Kyi and every night on the 360 Tour fans are being invited to wear the mask when the band play Walk On, which was written for her.''

Aung San Suu Kyi recently celebrated her 64th birthday, sparking a number of events which called for her freedom.

Actress Joanna Lumley raised a toast to the leader on behalf of charity Prospect Burma, and the Burma Campaign UK asked big names, including Prime Minister Gordon Brown, Sir Paul McCartney and Sir Richard Branson, to write birthday messages for her.
