At least three people have been killed and many others, including foreigners, injured in bomb blasts across the country.

One woman was killed and 10 people injured in a double bombing at the Thai beach resort of Hua Hin, Thai police said.

Nobody was injured in the first explosion at about 10pm local time on Thursday night.

A second explosion 20 minutes later and 50 metres from the first blast site killed a Thai woman and injured 10 people, including eight foreigners, local deputy police chief Samer Yousamran said.

The second bomb exploded near a busy intersection where bars are located and is popular with local and foreign visitors.

A motive for the bombing was not yet known, the deputy police chief said. The injured are being treated at a local hospital, he said.

Friday marks the birthday of Thailand’s Queen Sirikit, which is also Mother’s Day in Thailand.

Hua Hin is a popular upmarket Thai resort south of Bangkok where many people would have travelled to spend the holiday weekend.

In a separate incident earlier on Thursday, a bomb exploded at a market in the southern Trang province in Thailand, injuring six people. Police believe that explosion was related to a local dispute.
