Thailand increased its border security on Monday (February 1) as Myanmar's military took control of the country after detaining de-facto leader Aung San Suu Kyi.

Footage from Chiang Rai province in the north of the country shows soldiers manning checkpoints on roads that are popular crossing points near the town of Tachilek.

The extra measures in Thailand came in response to the unrest in Myanmar, where pro-military supporters held a rally in Yangon, Myanmar, on Sunday (January 31) afternoon shortly before leader Aung San Suu Kyi was detained and the army took power. They also disconnected phone and Internet services.

The supporters gathered close to the Shwedagon Pagoda in the city where they marched and chanted.
