Vrbetice, near the Czech Republic's border with Slovakia, is the last place you'd expect to play host to the murky world of international espionage. The village, with a population of around 300, is set deep in the countryside of central Moravia, in the country's far east. But things turned ugly in 2014 when a munitions depot at a former army complex of warehouses and factories jn the village -- sealed-off with barbed wire and “keep out” signs -- exploded in a towering fireball. Two employees were killed and much of the complex was levelled to the ground. The blast was such that farmers in nearby fields were reportedly thrown to the ground. Debris scattered for miles around.
