The Spanish Interior Ministry is concerned that the separatist group ETA may try to hatch a plan to attack during Spain’s presidency of the European Union, and has raised the terrorist alert level on Tuesday. 

The Ministry also said, that based on information provided by security agencies, the alert level was raised from level one to two on an overall scale of four. This level indicates that there is probability of a terrorist attack.

Interior Minister Alfredo Perez Rubalcaba had issued a warning on Monday that a “spectacular” attack or kidnapping may be planned by the ETA during Spain’ s EU presidency, in an attempt to prove that its strength has not dwindled over the years.

The Interior Ministry also said that there was an aggravated risk of attack during the festive season leading up to the New Year, and did not rule out an “international terrorist threat” as seen in Amsterdam when a US bound flight was tried to be blown up on Christmas Day.

Radio station Euskadi reported Tuesday that it had got hold of a police document according to which the ETA was planning an attack against a ministry or the police or kidnapping a senior minister.

Both the European Union and the United States consider Euskadi Ta Askatasuna, or ETA, as a terrorist organization.  It is also said to have killed 828 people over a span of 41 years, campaigning for autonomy in Basque regions of southwest France and northern Spain.
