Thai Resorts Rocked By Deadly Bomb Blasts

At least four people have been killed and more than 30 people injured in a series of blasts targeting tourist resorts in Thailand.

A wave of bombings were carried out in four main locations, with witnesses reporting at the site of one attack the devices had been hidden in plant pots.

They are believed to have been detonated remotely using mobile phones.

Popular tourist destinations have been targeted in the attacks

Investigators found ball-bearings at the scene which they think were put in the bombs to cause maximum injury.

Thai police said they had intelligence pointing to imminent attacks, but did not have details of when and where they would be carried out.

Following the blasts, the British embassy has updated its travel advice and warned holidaymakers there to "exercise extreme caution" and to avoid public places.

There are currently no indications that any Britons have been hurt in the explosions, although tourists from Germany, Italy, Austria and the Netherlands are among the injured.

Police in Thailand have blamed the attacks on "local sabotage".

Among the locations targeted included the popular tourist destination of Hua Hin and on the island of Phuket.

Hua Hin is famous as a regular retreat of the Thai King Bhumibol Adulyadej, who lives there in the Klai Kangwon Royal Palace, which translates as "Far from Worries Palace".

is a popular among both Thai and foreign holidaymakers.

Less than a week ago, Thais voted in a referendum to adopt a military-backed constitution.

It is being seen as the first test at the ballot box for Prime Minister Prayuth Chan-ocha, who seized power in a coup in May 2014.

For much of the past decade, Thailand has been plagued by political violence including bombings.

The latest blasts will come as a blow to the country's tourism industry, already hit by a bomb attack on a Bangkok shrine nearly a year ago.

Hua Hin Adventure Tours guide Natsupa Dechapanya said: "This ruins business. Hotels, restaurants, tours, we were already suffering, but this, it's going to ruin our lives."

She added: "This is the first time this has happened in Hua Hin. We think of this as a safe town, but now everyone is fearful. We feel like we're not safe."

Britons make more than one million visits to Thailand every year, according to the Foreign Office.

However, there are no current indications that any UK citizens were involved in the recent blasts.
