Authorities later sealed the Tambon Yaring Municipality and ordered residents and children to stay indoors, as they swept the area for more bombs in the morning.
At least 10 bombs went off in Pattani's Yaring district, including two at bank cash dispensing machines, wounding 11 policemen, officials said.
There were six explosions at around midnight in the municipality area, of which three were remote bombings but no one was injured.
Later a pipe bomb near a post office exploded killing one person and injuring one.
No group claimed responsibility for the attacks which authorities have blamed broadly on insurgent groups.
