Soviet spy hailed by Russia for 'saving Krakow' dies at 103

Russia on Thursday announced the death at 103 of veteran Soviet spy Alexei Botyan, whom it hailed as a hero for "saving" the Polish city of Krakow from the Nazis, although Poland disputes Moscow's version of events.

Russia's SVR military intelligence agency said Botyan, who lived in Moscow, had died after turning 103 on Monday.

Russian President Vladimir Putin expressed condolences, saying he always admired Botyan's "daring, patriotism and courage," said Kremlin spokesman Dmitry Peskov.

According to the SVR's account, in January 1945, "Lieutenant Alyosha" -- as he was affectionately called by locals -- helped blow up a munitions depot containing explosives the Nazis planned to use to destroy a dam and flood Krakow.

The SVR said Botyan considered his role in helping save the picturesque city the crowning achievement of his life.

Putin awarded Botyan Russia's highest medal, the Hero of Russia, in 2007, telling the veteran: "Old Krakow -- Europe's most beautiful city -- was preserved for Poland and the entire world culture in many ways thanks to your personal courage."
