MOSCOW (Reuters) – Russian commentators have challenged officials for not releasing full details about an accident on board a military submarine that killed 14 sailors.

The incident took place on Monday, according to the Defence Ministry, but was not officially disclosed until late on Tuesday. Nearly two days on, there was still no word on whether the submarine was nuclear-powered.

Some Russian media accused officials of starving the public of details and drew parallels with the dearth of official information during the meltdown of a Soviet nuclear reactor in Chernobyl in 1986.

The ministry said on Tuesday the sailors had been killed in a fire on what it described as a deep-water research submarine surveying the seabed near the Arctic.

The type of vessel was not specified and there were few details of the circumstances beyond the fact that it had been in Russian territorial waters and the fire had been extinguished.

“Absolutely nothing is known at the moment – who, what… I don’t understand one thing: why did a day go by and only then did they make the statement about the deceased?” said Yevgeny Buntman, an anchor for the Ekho Moskvy radio station. “Why don’t we know their names? Is this normal?”

The Bell, a news site often critical of the government, wrote: “Nearly a day without information about the accident in a nuclear facility and the need to look out for Norwegian statements about the level of radiation should have given a shudder to those who remember the Chernobyl nuclear power station.”

SECRET SUB

Norway’s authorities said on Tuesday they had not detected any abnormal radiation.

Asked on Wednesday if the vessel had a nuclear reactor on board, Kremlin spokesman Dmitry Peskov referred the question to the defense ministry.

He told reporters in a conference call that details of the submarine were classified, but that information had been provided in good time.

The media outlet RBC cited an unnamed military source on Tuesday as saying the submarine was an AS-12, which is powered by a nuclear reactor and designed to carry out special operations at extreme depths.

That vessel, nicknamed the “Losharik”, was launched in 2003 and is one of the most secret submarines in the Russian fleet.

Several hours before the official statement, blogger Yevgeny Karpov reported a fire on a vessel belonging to the Northern Fleet, but he then took down the report at the fleet’s request, he told the Meduza news site.

The fire is one of the deadliest submarine accidents since August 2000, when the nuclear-powered Kursk sank to the floor of Barents Sea, killing all 118 men aboard.

Authorities then, and in particular President Vladimir Putin, who was at the beginning of now almost two decades as president or prime minister, came under fire for their slow response and shortcomings in the rescue operation.
