Two killed in Spanish resort explosion

Police officers examine what was left of a car bomb that exploded Sunday in Santa Pola, Spain.

MADRID, Spain, (CNN) -- A car bomb killed two people and wounded 40 others Sunday in front of a Civil Guard barracks in the southeastern tourist resort of Santa Pola, a government official told CNN.

The bomb exploded at 8:30 p.m. (2:30 p.m. ET) near a bus stop, killing the 6-year-old daughter of a member of the paramilitary Civil Guard member and a man in his late 50s, the official said.

The girl was taken to a hospital, where she died. The man died at the scene, the official said.

No group has claimed responsibility, but the bomb appeared to bear the hallmarks of an attack by ETA, the Basque separatist group, said the official, who asked not to be identified.

Fifteen people were taken to area hospitals and 25 others were treated in Santa Pola at or near the scene of the explosion, which blew out windows and tore apart the facade of a three-story building.

The government official told CNN it was not certain there was a warning call before the blast, but he said there apparently was a call made subsequently to authorities warning of a potential second bomb.

The area -- in old-town Santa Pola used primarily by local residents, not vacationers -- was cordoned off but no second bomb was found, the official said.

Santa Pola is on the Mediterranean coast, about 12 miles (20 kilometers) from the city of Alicante.

ETA has killed more than 800 people since 1968 in its drive to carve out an independent state in Basque areas of northern Spain and southwestern France. The United States and European Union, which includes Spain, list ETA as a terrorist organization.

It has frequently targeted installations of the Civil Guard, a paramilitary national police force. It also has targeted areas of the lucrative tourist industry, most recently in June when it detonated a series of devices near beach towns in southern Spain.

The most recent fatality blamed on ETA, and the only one this year, was the shooting death of a local Socialist councilman last March in the northern Basque region.

Senior Spanish officials, including the interior minister, were expected to visit the scene of the explosion later Sunday, the official told CNN.
