A court in military-ruled Burma has sentenced a popular comedian and pro-democracy activist to 45 years in prison. Three associates and a Buddhist monk also received lengthy sentences.

Authorities detained Maung Thura -- known by his stage name, Zarganar -- earlier this year after he organized private aid deliveries to victims of Cyclone Nargis. He was sentenced Friday for violating the Electronics Act, which regulates all forms of electronic communication. He still faces additional charges.

The court also sentenced three of Zarganar's associates. A prominent sports journalist, Zaw Thet Htwe, and a video journalist, Thant Zin Aung, were each sentenced Friday to 15 years behind bars, and another man, Tin Maung Aye, was jailed for 29 years.

Also Friday, Burmese authorities sentenced a monk, Ashin Gambira, who led pro-democracy protests last year on additional charges, bringing his total jail time to 68 years.
