Budapest: Hungarian police evacuated thousands of people in central Budapest on Tuesday where experts prepared to defuse a huge bomb found on a construction site.

The two-tonne bomb is one of the biggest found in the Hungarian capital, which was heavily bombed by the Allies during the Second World War.

About 16,000 people live in the area where the bomb was found, said Tamas Bansaghi, deputy mayor of the affected 9th district.

He said defusing it might take well into the night because it is embedded in concrete in a deep hole.
