Fourteen seamen have died in a fire on a deep submersible, Russia's defence ministry said Tuesday, the latest in a string of disasters and accidents to hit the country's navy.
The tragedy in the far north has echoes of the sinking of the Kursk submarine in 2000 that claimed the lives of 118 personnel and shook the first year of Vladimir Putin's presidency.
"On July 1, a fire broke out during biometric measurements on a scientific research deep-sea submersible," the defence ministry said.
Fourteen crew died as a result of poisoning from the fumes of the fire in Russia's territorial waters, a ministry spokeswoman confirmed to AFP.
The fire has been put out, the ministry said, adding an investigation was under way.
"The investigation is being conducted by the commander-in-chief of the navy." The research was conducted to study areas near the seabed and the seabed itself of the ocean in the interests of the Russian naval fleet, according to the ministry.
The vessel is now situated at a military base in the closed northern city of Severomorsk which is located on the Kola Peninsula above the Arctic Circle.
