Explosive devices struck eleven petrol stations and associated service sites across Thailand’s three southernmost provinces late on Saturday night, local authorities confirmed.

The blasts — widely condemned by political leaders and security officials — occurred in Pattani, Yala and Narathiwat, areas that have periodically faced insurgent violence.

Initial reports from provincial sources indicate that the explosions targeted petrol station premises and adjacent convenience outlets.

The coordinated nature and timing of the attacks prompted swift condemnation from senior political figures, who described the violence as an assault on public safety and regional economic stability.

In a public statement, a leading party head underscored the intolerable impact of such violence on local communities and urged security forces to identify and apprehend those responsible.

“These acts do more than damage property; they erode confidence, disrupt daily life and threaten economic confidence in the region,” the leader said.

Calls were renewed for peace and for the issue of southern unrest to be elevated as a national priority.

Security agencies have launched investigations at each site and increased patrols throughout the affected provinces.

Authorities are reviewing surveillance and forensic evidence to determine the identities and motives of the perpetrators.

No definitive claim of responsibility had emerged at the time of reporting, and casualty figures have not been independently confirmed.

State security forces emphasized that they are pursuing all leads and coordinating with local command units to prevent further attacks.
