Two blasts follow ETA warning
MADRID, Spain (CNN) -- Two small bombs exploded Saturday in northwestern Spain slightly injuring four people after warning calls were made in the name of the Basque separatist group ETA, an interior ministry spokeswoman told CNN.
The bombs exploded in the village ports of San Xenxo and Baiona in Pontevedra Province. It is the third weekend of explosions on Spain's northern Atlantic coast, which is generally crowded with tourists during the August vacation season.
In the town of San Xenxo, two Portuguese and two Spaniards were treated for injuries, the central government's interior ministry spokeswoman in the province said. One suffered injuries to the shoulder and the other injured an ear.
The spokeswoman said the two bombs were apparently in trash bins. Only minor property damage occurred in the town of Baiona.
Two warning calls were made ahead of the blasts -- one to the Basque newspaper, Gara, which frequently receives warning calls in the name of ETA.
And a second call came to Faro De Vigo, a newspaper, which publishes in the area of Pontevedra where the bombs went off, the government spokeswoman said from Pontevedra.
ETA has been blamed for more than 810 killings since 1968 in its fight for an independent Basque homeland. The group is listed as a terrorist organization by the U.S. and the European Union, and has for years threatened tourists.
ETA is also blamed for the series of small bombs that exploded in recent weeks in Spain's northern coastal area. Of those earlier bombs, just one person was reported injured.
