A German bomb disposal team yesterday successfully defused an unexploded World War II bomb that had forced the evacuation of 18,500 people in the city of Ludwigshafen. The 500-kg (1,100-pound) aerial bomb, thought to have been dropped by American forces, was discovered during construction work earlier in the week.

"Good news: the bomb has been defused! Citizens may return to their homes," the city of Ludwigshafen said on its official Twitter feed. It also posted a picture of the freshly unearthed, corroded bomb, strapped to a pallet before being removed from the area. Authorities in the western city had ordered all those living within a 1,000-metre (0.6-mile) radius of the bomb site to leave their homes from 08:00 am (0600 GMT) as a precaution ahead of the defusing operation. It took the bomb squad just over an hour to complete the delicate task, and the all-clear was given shortly after 2:00 pm. More than 70 years after the end of World War II, Germany remains littered with unexploded ordnance, a legacy of the intense Allied bombing campaign against Nazi Germany.
