Thai police say at least 18 bombs have exploded at banks in the restive southern province of Yala, killing at least one person and wounding several others.

Officials suspect militants detonated the bombs, which exploded Thursday at or near commercial banks in Yala's provincial capital and nearby districts.

Islamist insurgents have staged a lengthy series of attacks in Yala and two other Muslim-majority provinces in southern Thailand, Narathiwat and Pattani, since January 2004. The provinces were a Malay sultanate until Buddhist Thailand annexed them a century ago.

More than 1,400 people have been killed since the insurgency erupted.
