Continuing investigations into the terrorist attack on the island of Mallorca on Sunday, has now revealed that there is likely to have been a total of four bombs that exploded in various locations.

At around 12:00 noon at the bar Nica on Avenida Comte of Sallent, in the heart of Palma, an explosion occurred, but at the time it was believed to have been caused by a build up of gasses and not a bomb.

Being that this explosion was triggered at 12:00, it would mark this location as being the first of four attacks during the day.

Police officers are examining the bar today, which has been closed since Friday, in order to confirm the cause of the explosion.

Meanwhile, the investigation is continuing to locate the terrorists responsible for this attack, as well as previous attacks on both the island and mainland Spain.
