A victim of a huge explosion in north-east Spain died when a boiler cover flew three kilometers and hit a building, it’s emerged.

Tarragona’s mayor, Pau Ricomà, said the boiler cover had smashed through the window of an apartment, causing its floor to fall and killed a man living underneath. He described the event as “almost unbelievable”.
