A spate of arson attacks hit Thailand's unrest deep south on Friday, a continuation of the previous day's violence spree.

Beginning on early Friday, insurgents launched nine arson attacks against public buildings in the southern province of Pattani, some 1,000 kilometers south of Bangkok.

Targets of the attacks included kindergarten, technical school, telephone booths and government office building, local police told Xinhua stringer. No casualties were reported in the attacks.

It's the second day that Pattani has fallen into intensive trouble-making violence by militants.

More than 10 arson attacks and eight bombs were reported in eight of Pattani's 12 districts on Thursday, injuring four people.

Insurgents also scattered road spikes on highway and sprayed separatist slogans on public buildings.

A spate of violence also hit the neighboring provinces of Songkhla and Narathiwat, which witnessed four arson attacks and one bomb explosion on late Thursday and Friday.

One soldier was seriously injured when a bomb exploded on his way of patrol in Narathiwat on Thursday night.

In face of the intensified violence, Deputy Prime Minister and Interior Minister Chidchai Wanasatidya is scheduled to fly to the southernmost provinces later Friday.

All the incidents are believed to have related to the unceased violence that has plagued the region since the beginning of last year.

The authorities have blamed revived local separatists for the ongoing violence, which has claimed around 700 lives in the past 17 months.

Though the government has beefed up security in the deep south, insurgents are still carrying on attacks, planting bombs, setting fires or shooting people on an almost daily basis.
