BANGKOK, Thailand (AFP) —Dozens of coordinated arson and incendiary attacks across Thailand's insurgency-hit south late Saturday left two people injured and damaged government property, the military said.

A local government office building, a 7-Eleven convenience store and a stolen vehicle were burned in the 51 attacks, according to the military's Internal Security Operations Command (ISOC) and local media reports.

"Multiple coordinated incidents aimed at creating unrest occurred in various locations across the southern border provinces" from around 8 p.m. to midnight on Saturday, ISOC said in a statement.

Most were in Narathiwat province, where two civilians were reported injured and an overnight curfew was imposed, while other attacks occurred in neighboring Yala and Pattani provinces, ISOC said.

Since 2004, a low-level conflict has simmered in the southernmost provinces of Buddhist-majority Thailand, killing more than 7,000 people, as rebels in the Muslim-majority region battle for greater autonomy.

No group has claimed responsibility for Saturday's attacks.

Narathiwat Governor Boonchuay Homyamyen told local media that authorities were investigating the sites of the attacks on Sunday, including the local government office and telecommunications towers and electrical poles.

There were no further attacks reported on Sunday morning, Boonchuay said, adding he did not have details on the injured.

The Narathiwat military command earlier announced a curfew from Saturday night until 6 a.m. Sunday.

A vehicle was stolen from the office of a subdistrict administrative organization in Narathiwat during one of the attacks that left the building in flames, ISOC said.
