Spanish police have said that an explosion at a house in the town of Alcanar yesterday, which killed one person and injured six others, was linked to today’s attack in Barcelona.
The explosion took place at a house in Alcanar, some 120 miles south of the Barcelona.
It occurred around 11.15pm Wednesday night, and was believed to have been caused by the more than 20 butane gas canisters stored in the property.
A second explosion took place after emergency services rushed to the scene, injuring six police officers and two firefighters as they sifted through rubble.
A police source said it is believed the residents in the house were preparing explosives using gas cylinders. Police said it was possible a second person was dead among the ruins of the house.
It is thought that prior to the explosion yesterday, the terrorists involved in the Barcelona attack had been planning to fill the rented van with the butane canisters to detonate when the vehicle came to a stop.
