At least 19 leaders of Thailand's anti-government protesters, known as the Red Shirts, have been charged with terrorism following their long-running demonstration in the centre of the capital, Bangkok.

Most of them have been in custody since the rally ended in May.

However, two years after the rival so-called Yellow Shirt pro-government protesters blockaded Thailand's two main airports in a separate protest, their leaders have only just reported to police to answer charges.

Al Jazeera's Wayne Hays reports from Bangkok on the perceived double standard.
