DEBKAfile reports that Russian websitesThursday morning began running unconfirmed reports that Russian President Vladimir Putin had suddenly died. This has not been confirmed by any official in Moscow. But a short announcement of Putin’s death was seen briefly on Prime Minister Dmitry Medvedev’s website early Thursday, only to be removed after 20 minutes. According to officials in Moscow, Putin was expected in Kazakhstan Thursday for meetings with its leaders, but failed to turn up.
