A star of the popular American TV show “CSI: Crime Scene Investigation” urged the world Monday to turn its attention to the suffering of people in military-ruled Myanmar.

Eric Szmanda spoke to reporters after a three-day visit to the Thai-Myanmar border, where he met refugees fleeing an ongoing campaign by the Myanmar military against the Karen ethnic minority.

“One and a half million people have been forced from their homes, women are systematically raped, men and children have been forced into slave labor,” he said.” It’s time to say, `Enough is enough.’”

Admitting that until recently he knew little about events in the Southeast Asian nation, Szmanda said he would share his experiences with friends and co-workers in Hollywood “and anybody who will listen.”

Szmanda plays Greg Sanders on the Emmy Award-winning CBS television series, ranked in the top three most-watched TV programs around the world every year since its debut in 2001.

His trip was sponsored by the US Campaign for Burma, an activist group of Americans and Myanmar exiles based in Washington.

Szmanda called on the military in Myanmar, also known as Burma, to end its attacks on the Karen in the country’s eastern region. Some 3,000 Karen villages have been destroyed in the offensive, according to several non-government organizations working along the border.

“The U.N. can do a lot on Burma, countries in this region can do a lot on Burma, the United States and Europe can do a lot on Burma, but they need to start to speak out, regularly and quickly and with urgency. I think that’s the most important thing that we can do,” he said.

During the trip, Szmanda visited the clinic of Dr. Cynthia Maung, who has treated thousands of her fellow refugees over the past two decades and has been called “The Mother Theresa of Burma.”

Szmanda said his visit to the clinic was “one of the most inspiring and shocking things that I have ever seen.”

Myanmar has been under military rule since 1962, the latest junta emerging after a brutal 1988 crackdown on pro-democracy protests. The military has been widely accused of atrocities against ethnic minorities and of suppressing the democracy movement led by detained Nobel Peace prize winner Aung San Suu Kyi.
