Two small bombs blamed on Basque separatist group ETA exploded at tourist resorts in southern Spain yesterday. No injuries were reported, but more than 10,000 people were evacuated from a harbour area. It is the height of the summer tourist season in Spain. The first blast occurred on a beach in Guadalmar and a second device exploded at a tourist marina parking lot in Benalmadena Costa. Both towns are around 550km south of Madrid in the Costa del Sol resort area on a stretch of coastline popular with foreign tourists, especially the British.A caller who said he spoke in the name of ETA warned the fire department in the beach resort of Benalmadena that three bombs would explode, the ministry said. He said bombs had been placed in Guadalmar, Benalmadena and on a highway linking Malaga to its international airport.
