ETA bombs Spanish highway

Basque separatists ETA detonated a bomb among highway roadworks in Spain's Basque region yesterday, damaging construction vehicles and cabins but causing no injuries, the regional government said.

It was ETA's first attack since the arrest last week of what the Spanish government said was its most active guerilla unit, blamed for killing a civil guard and a string of attacks on police stations.

The bomb exploded in an expansion project on the A-8 highway at Orio, west of San Sebastian, damaging equipment belonging to construction firms Acciona and Fonorte, a Basque business confederation said.

Police alerted workers before they arrived at the job site, a Basque government spokesman said, adding that it was unclear when the bomb went off.

"The explosion caused significant damage to six work cabins and hit four vehicles," a government spokesman said.
