PRAGUE, Nov. 1 (Xinhua) -- Four workers were seriously injured in gunpowder blast in a Czech explosives factory in Pardubice, 150 km east of Prague, on Friday morning, according to local media reports.
One of the victims suffered burns of 90 percent of the body and is in a critical condition, and the others are in serious conditions.
The plant is a part of the state-owned Explosia, a company known as the producer of the Semtex plastic explosive.
