Dozens poisoned by ammonia after train derails in Southeast Serbia

Dozens were poisoned after a freight train carrying ammonia derailed, spilling its cargo in southeastern Serbia, officials said.
According to authorities, the ammonia leak caused 51 cases of poisoning in the city of Pirot.
The train derailed causing the leakage of ammonia and the dispersion of a large amount of gas into the atmosphere, the Interior Ministry said in a statement.
The 20-carriage train was transporting toxic materials from neighbouring Bulgaria, officials said.
Ammonia gas leaks can be flammable and can cause serious injury or even death.
