Several people were injured Wednesday in Munich after an unearthed World War II-era bomb exploded, German media reported.
Police said that the blast occurred at a railway construction site near the city centre, Belga News Agency reports.
Three people suffered minor injuries, and another was seriously injured but is not in a life-threatening condition, according to the Dutch news agency ANP.
A large plume of smoke is rising from the site, according to the German daily Bild. Rail traffic surrounding Munich’s main railway station was suspended.
Experts from the explosive disposal service were dispatched to investigate the cause of the incident. According to Bavaria’s Interior Minister Joachim Herrmann, the 250-kilogram aerial bomb was hit during construction.
It is not known why the bomb was not discovered before work began in the area. The Munich authorities regularly carry out analyses to determine the location of the bombs, which are remnants of the Second World War.
