"I appeal to all countries in the world to do their duty of exerting pressure on Sri Lanka to release Eelam Tamils languishing in jails there for many years," he said in a statement.
"The nations should realise that human rights are being trampled by Sri Lanka by hoodwinking them", he said.
Alleging that Eelam Tamils were imprisoned in Sri Lanka based on "false cases" in 14 jails, he said Tamil prsioners in such jails were on a hunger strike for the past three days seeking their release.
"I appeal to Tamil organisations (in Sri Lanka) to make the general strike a success on November 13," he said.
