Are these people really a threat to Thai national security?

With more than half the population registered as Facebook users, Thailand has one of the highest rates of social media use in the world.

The military junta that rules the country has, like other governments in the region, expressed concern about the spread of fake news online.

It's adapted draconian laws against computer crimes to impose heavy penalties on those accused of uploading false or distorted information.

While the country may return to democracy with an election next year, Thai government critics now risk being accused of "fake news" – and having these laws turned against them.
