Two small explosive devices exploded in resort towns in northwestern Spain on Saturday, news reports said. One person was slightly injured in one of the blasts in Sanxenxo in the province of Galicia, Spanish news agency EFE reported. Another device went off in Baiona, a coastal resort about one hour's drive from Sanxenxo, the agency said. The blasts happened at a yacht club and a sports marina and were preceded by a telephone warning to the Basque newspaper Gara, the route ETA usually employs to warn of attempts, EFE said.
