Nearly 3,000 residents were evacuated from the heart of Munich on Tuesday before explosives experts detonated the remains of an undetonated, 550-pound World War II bomb, Andy Eckardt of NBC News reports.

Bales of straw which had been placed around the bomb to cushion the shock of the detonation were set ablaze and thrown through the air by the detonation, according to the European Pressphoto Agency. Some of them landed on the roofs of neighboring buildings and ignited fires.
