A hotel was badly damaged and one person killed after Thailand was hit by another bomb blast.
At least 30 people were also injured outside the city of Pattani, which is in the restive Muslim majority southern region where bomb attacks have been taking place for several years.
"So far there is one killed and more than 30 injured. The hotel building was considerably damaged," said Major General Thanongsak Wangsupa, Pattani provincial police commander.
Pattani is not a popular tourist centre but it has nevertheless heightened concerns for overall security in the country after several resort towns were attacked in a wave of bomb blasts earlier this month leaving four dead and 37 injured.
Embassies have issued travel warnings for years for the far south of Thailand where Muslim insurgents have waged a violent struggle for autonomy in the Buddhist dominated country.
Several thousand people have died as a result of bomb and gun attacks since 2004, which has mostly been centred in the region itself, with little impact on the tourism industry.
Authorities are still seeking the perpetrators behind the bomb attacks that targeted tourist towns on 11-12 August, with Chaktip Chaijinda, the national police chief, saying he believed they have links to militants in the South.
