Information has emerged that a Belgian policeman gave a tip to Catalan police in 2016 about the alleged mastermind of the Barcelona attacks who was killed in a blast that destroyed a house in Alcanar. The informal tip-off said the Moroccan imam, Abdelbaki Es Satty was a suspicious person although no links were found at the time to tie him to Islamist militancy.
Police investigating the blast believe the cell was preparing explosives for an even bigger attack and found over 100 tanks of butane gas and materials at the house.
A Spanish High Court Judge has released another of the four suspects over the attacks, Salh El Karib, on certain conditions including a ban on leaving Spain and handover of his passport.
Meanwhile, footage has emerged of three of the Barcelona terrorists caught on a surveillance camera at a petrol station just hours before they carried out an attack on civilians in the city of Cambrils. The three were later killed in a shoot-out with police.
Some 40 religious and non-religious communities took part in an interreligious ceremony at the Maritime Museum of Barcelona, on Thursday, to commemorate the victims of the recent attacks. The ceremony was headed by the Catalan President and the Mayor of Barcelona.
