At least five were killed and 25 injured in an explosion when a cargo train carrying propane-butane derailed on Saturday in Bulgaria's Hitrino village, AFP reported.
The blast occured at 5:37 am (0337 GMT) when it derailed at the Hitrino railway station and the two last tankers hit a power line, local police spokeswoman Assia Yordannova reported.
At least three of the victims remain in critical condition and the number is likely to rise, authorities said.
