BANGKOK, Oct. 11 (Xinhua) — Police have been put on full alert in the wake of reported bomb scares in several provinces in upper southern Thailand, police said on Tuesday.

Eighth Provincial Police commissioner Pol. Lt. Gen. Tesa Sirivato issued the alert warning for the police in the upper southern provinces including Hua Hin, Surat Thani, Chumporn and Ranong where several tourist destinations are located for fear that mysterious blasts and other untoward incidents might possibly occur anytime this month.

The police commissioner's full-alert orders were largely based on tip-offs from unidentified sources, however.

Security measures will be stepped up at railway stations, bus terminals, airports, piers and major tourist spots throughout the upper southern region to keep the mysterious bombings from recurring following those which killed and injured several people last August, the police said.

Prime Minister Prayut Chan-o-cha declined to comment on unconfirmed reports that bombings and other violent acts might not only occur in the upper southern part of the country but also in and around the capital city. He said he had instructed the authorities to round up the latest security situation for briefing and remain on full alert.
