MADRID, Spain (CNN) -- Four explosions struck a new, soon-to-be-operational electrical power plant in northern Spain on Tuesday, shortly after warning calls were made in the name of the Basque separatist group ETA, a Basque regional police spokesman told CNN.
There was no immediate confirmation of injuries, and damage was being evaluated, the spokesman said.
After the warning calls to the Basque newspaper Gara and to the Basque emergency road service DYA, police rushed to the plant, in the Basque city of Amorebieta, and evacuated the workers.
The explosions occurred in quick succession between 2:05 pm and 2:15 pm local time.
The gas-fired thermal power plant is in a testing phase and not yet on line.
ETA, listed as a terrorist group by the United States and the European Union, is blamed for more than 800 killings in its 37-year fight for Basque independence in northern Spain.
If often chooses to make warning calls and when it does so, the Gara newspaper typically gets the call
The group has also claimed responsibility, in warning calls, for several car bombings this year in Madrid that caused injuries and caused property damage.
Spanish Parliament recently approved a Socialist government proposal to hold talks with ETA if it would first renounce violence and lay down its arms.

Four explosions have rocked a brand new, soon to be online power station in Spain's Basque reigon in the city of Amorebieta. 

Shortly before the blasts, warning calls were made to Basque newspaper ''Gara'' and the Basque emergency road service known as DYA, police rushed to the scene and evacuated workers. The calls were made by the Basque separatist group ETA.

There are no confirmations of injuries or structual damage from the blasts at the moment. Spanish radio however reports that there were no injuries and some minor structual damage. Witnesses to the explosions say they were small.

Warning calls before blasts are common by ETA, usually ''Gara'' will get the call.

The plant is run by ESB International.
