VIDEO | Tourist killed after two boats collide off Thailand's Phi Phi Islands

The 55 passengers and crew who were on the tour boat were thrown overboard as it capsized. All were subsequently pulled out of the water by responding police and rescue personnel.

Tragically, a female passenger who was found in critical condition succumbed to her injuries after being brought to hospital. The news was confirmed by both local media and Yegor Ivanov, the Russian Consul-General in Phuket, who said that the deceased victim was an 18-year-old Russian national.

The tour boat's three crewmembers and 21 other passengers suffered injuries, though none are considered to be life-threatening.
