ONE of Vladimir Putin's war planes dropped a bomb on a Russian city tonight - blowing a massive 65ft crater in the street. Residents said they heard a whistling noise before a blast erupted beside a block of flats in Belgorod, only 25 miles from the border with Ukraine. In a statement, the Russian Ministry of Defence said: "As a Sukhoi Su-34 air force plane was flying over the city of Belgorod there was an accidental discharge of aviation ammunition."
