More than 50 arson and incendiary attacks have struck Thailand’s insurgency-hit south, with authorities describing the incidents as an attempt to create unrest and pointing out that they are likely coordinated.

The attacks occurred between 8pm and midnight on August 22 across the southern border provinces, according to the Internal Security Operations Command. Most were reported in Narathiwat on the border with Malaysia, while others took place in Yala and Pattani, according to the BBC. 

At least two people were confirmed injured. Targets included a local government building, a convenience store, a stolen vehicle and several telecommunications towers.

At the same time, the Bangkok Post reported that two women were hurt after a bomb exploded in Narathiwat’s Muang district. Security officials also warned residents to avoid touching suspicious objects.

Authorities introduced an overnight curfew in Narathiwat, which was lifted the following morning. No further attacks had been reported by then, and no group has since claimed responsibility.

The violence comes amid a long-running insurgency in Thailand’s predominantly Muslim southernmost provinces. The conflict, which began in its current form in 2004, has killed more than 7,000 people as ethnic Malay Muslim rebels seek greater autonomy from the Buddhist-majority state.

The Barisan Revolusi Nasional is regarded as the main insurgent organisation and while peace talks facilitated by Malaysia have taken place since 2013, they have repeatedly stalled amid political changes in Bangkok and divisions among the parties.

In July, five soldiers were killed in a gun and bomb attack on a checkpoint in Narathiwat, leading authorities to postpone planned peace discussions.
