Security forces in southern Thailand are on heightened alert for the eight anniversary of a military crackdown that killed 85 people.

In 2004 hundreds protested against the detention of six men, suspected of involvement with armed Muslim groups fighting for independence from the Buddhist majority of Thailand.

Al Jazeera's Wayne Hay reports from Narathiwat province on the security alert coinciding with what is now known as the Tak Bai massacre.
