Following a series of coordinated bombs over the last 24 hours in Thailand, the Foreign Office has advised people in tourist areas to "exercise extreme caution, avoid public places and follow the advice of local authorities".
Four bombs exploded in Hua Hin, a tourist town south of Bangkok, killing two people, while two blasts have occured in Surat Thani, killing one person, the BBC reports.
Blasts also took place in the beach town Patong in Phuket, in Trang where one person died, and in Phang Nga.
Tourist locations appear to have been targeted in the blasts, occuring on Friday, which was designated a public holiday to mark Queen Sirikit's birthday.
Police said they have detained suspects and have ruled out international terrorism.
