Ukraine - Gunpowder Accident - NYTimes.com Eight people were injured in a small fire on a trolley car on Monday in the city of Dnipropetrovsk. Local prosecutors said the accidental fire occurred when a passenger dropped a bag of gunpowder, causing it to ignite. The accident renewed fears of terrorist attacks in the city, where four explosive devices detonated in late April, wounding 38. "This was not an explosion - this was an ignition of gunpowder that is not a terrorist action," a prosecutor, Natalya Marchuk, told the Interfax news agency, adding that an investigation would be conducted.
