Russian TV broadcasts 'secret' nuclear weapon plans
Russian plans for a new submarine-launched nuclear torpedo shown on state-controlled TV were secret and should never have been aired, the Kremlin has said.
The video showed a document describing a weapons system called Status-6, which it said would cause radioactive contamination to make coastal areas unsuitable for military or economic activity "for a long time".
It was shot over a military officer's shoulder during a meeting with President Vladimir Putin, and broadcast on NTV and Channel One.
The channels later removed the footage.
Mr Putin's spokesman Dmitry Peskov said: "It's true that some secret information was caught by the camera and therefore it was subsequently removed. We hope this will not happen again."
The appearance of the video on Kremlin-controlled TV channels raised suspicions it was done deliberately to alarm the West.
Mr Putin has held four meetings on defence issues in as many days this week, reflecting the close attention he is paying to military modernisation at a time of heightened tensions with the United States and Europe over the crisis in Ukraine.
At Monday's meeting, he said Russia's military modernisation programme had been successfully implemented, with defence plants churning out new jets, missiles, navy ships and other weapons.
