Confiscated fireworks caused an explosion at Egypt's Galaa Court Complex in downtown Cairo during a case investigation at the prosecution office on Thursday.
A member of the Al-Zaher general prosecution staff was examining the fireworks, which had been siezed by police and was being held as evidence, when it set off a minor explosion.
The prosecution office caught fire, leaving several of its windows smashed. Three people were slightly injured, Al-Ahram's Arabic-language news website reported.
