Four injured in bomb attacks on Thailand petrol stations

Assailants detonated bombs at nearly a dozen petrol stations in Thailand's Deep South early Sunday, injuring four people, the Thai army said.

Authorities did not announce any arrests or say who may be behind the attacks. Thailand's Prime Minister Anutin Charnvirakul told reporters that security agencies believed the attacks were a signal timed with elections for local administrators taking place on Sunday, and not aimed at insurgency.

The Thai army's commander said he ordered security measures raised to the maximum level in all areas, including at road checkpoints and borders.
