  • 21 Jun 2022

Synopsis: In this special series, The Straits Times dives into some of the greatest unsolved mysteries in South-east Asia, and examines the underlying issues that they exposed.

In this episode, we investigate the source of the red and orange fireballs that emerge from the Mekong River once every year.
