Authorities have urged visitors to the popular Thai resort island of Koh Phangan to take care when swimming after a five-year-old French boy died from a sting by the world's most toxic jellyfish.
The boy, who was holidaying with his family, died on Saturday evening after he was stung by a box jellyfish – regarded as one of the deadliest creatures on earth.
While stings from the species are rare, they are potentially fatal, prompting police on Koh Phangan to urge hotels and local authorities to warn tourists to be careful in the water.
