A wave of attacks including bomb explosions and assaults on power grid hit Thailand's deep south early Friday, but causing no casualties, local media reported.

According to Thairath Newspaper, the spring of attacks were scattered across 19 districts in the country's southernmost areas, namely Yala, Pattani, Narathiwat and Songkla provinces. A total of 52 power poles were destroyed, plunging the area into darkness for hours.

Local reports said a series of bombing rocked Pattani, Yala and Narathiwat at midnight. Pattani was seriously affected as 11 small bombing were found there.

Military officials confirmed to local media that there were no attacks on military targets and no injuries nor deaths in the attacks.

Pattani, along with Yala and Narathiwat are the three southernmost provinces that were haunted by explosions.

The attacks happened just few hours after Thai King Maha Vajiralongkorn signed the country's 20th constitution on Thursday.

The draft charter, overwhelmingly approved in a referendum in August last year, was strongly opposed by the three border provinces.
