UNHCR and Save the Children aid workers arrested in Sri Lanka

I would like to check the details on this story from a Sri Lankan newspaper. I have not found anything so far on the web. It's a disturbing development.

Does anyone have any further information?

Tigers in INGO clothing

By Tissa Ravindra Perera
Now that the Wanni battle is over, Intelligence sleuths are fully engaged in tracking down and arresting Tiger hit-teams who had infiltrated the city, to carry out attacks.

Military and Police Intelligence are not only successfully tracking down the Tiger hit-teams, but are also in the process of uncovering their sinister plans to create mayhem in the country.

Police Intelligence made a major breakthrough last week, when they bared a Tiger plot to assassinate President Mahinda Rajapaksa, which had been hatched with the connivance of two INGO officials and two local politicians.

This story was published in the June 28 edition of the Sri Lankan newspaper The Nation.

Is there any confirmation, or further material you can share?
