A major police operation is underway on the Spanish island of Mallorca after three small bombs exploded in tourist hot-spots.No one was injured in the blasts. A telephoned warning, said to have come from the Basque separatists ETA, was given about two hours before the first device went off in Mallorca’s capital. Police sealed off the beachfront La Rigoletta restaurant and the area nearby where two of the bombs were left. The third was in a shopping area and was safely detonated by police. All three were low-powered devices, possibly indicating that they were not designed to cause widespread damage, although all could have caused significant injuries. Ramon Socias of the Balearic Islands Council said: “We are working on the hypothesis that the bombers are still on the island and have not left due to the reinforced police checks at ports and airports. Today’s events indicate they are still here.” The attacks follow last month’s bombing, now claimed by ETA, which left two civil guards dead. This time it seems the target for the bombers was the island’s tourist industry. With security on the island already tight after the July bombings, tourists are getting used to the heightened police presence. A government spokesperson said it was too early to tell if the bombs would harm tourism in the Balearic islands.
