4 people were injured when a World War 2-era bomb exploded at a railway construction site near the Donnersberger Bridge of Munich, Germany. Local media outlets report that one person was seriously injured after the blast nearly tore off his leg, but after doctors operated on him for 4 hours to reconstruct his leg, his condition is now stable. Fire brigades and bomb disposal units say that the 250 kilogram (about 551 pounds) bomb exploded as construction teams were drilling to build a tunnel at the site.  

Following the explosion, rail travel in much of Munich was temporarily halted. Rail operator Deutsche Bahn initially suspended travel to and from the central station, but local reports suggest that some services have resumed. Meanwhile, Bavarian Interior Minister Joachim Hermann told media that "It has to be investigated why no-one spotted this bomb earlier".  

Unexploded World War 2-era explosives, often dropped by British, American, and other allied forces, are frequently found in Germany, often prompting large evacuations. However, most are successfully defused by experts without exploding and safely disposed. Typically, major construction projects take care to search for unexploded ordnance prior to commencing work.
