TUNNEL WORK TRIGGERS WWII-ERA BOMB NEAR STATION

Four people were injured when an old aircraft bomb exploded at a bridge near Munich's busy main train station on Wednesday, police said on Twitter.

The Munich fire brigade said one of the people was seriously injured.

More than 2,000 tonnes of live bombs and munitions are discovered each year in Germany, more than 70 years after the end of the Second World War.

British and American warplanes pummelled the country with 1.5 million tonnes of bombs that killed 600,000 people.

Officials estimate that 15 per cent of the bombs failed to explode, some of which were buried six metres deep in the ground.

The explosion happened as the site was being drilled to build a tunnel, police said, adding the area had been cordoned off.

“There is no danger outside this area,” police said.

Explosives experts were summoned to the site to examine the remains of the bomb, the fire brigade said.

Due to the blast, rail travel to and from the main train station was suspended, according to rail operator Deutsche Bahn.
