During the pro-democracy Saffron Revolution (2007), thousands of Buddhist monks were widely involved in the protests. When the military broke up the protests, many monasteries were raided and numerous monks were jailed, beaten, tortured and even killed. Others were sent to isolated labor camps. U Gambira was an influential activist monk of the Burmese pro-democracy movement and is the leader of the All Burma Monks' Alliance (which was founded by U Nat Zaw). The Burmese monks were supported by a regional network of Buddhist activists from Sri Lanka, Thailand, Malaysia and Singapore. During and after the crackdown, many such as U Nat Zaw managed to leave the country.
