Security forces have stepped up their efforts to seek out and detain the terrorists responsible for five ETA separate bomb attacks in Spain at the weekend.
Prime Minister Mr José Marìa Aznar said the attacks were deliberately planned to coincide with the EU summit in Seville.
"The terrorists tried to create a climate of fear and destruction. It was an attack against a Europe which has no space for them and which has rejected them," he said.
However, officials do not rule out that the bombs also marked a dramatic start to ETA's annual "beach bomb" campaign in tourist areas similar to ones in previous years when terrorists attacked Spain's vital tourist industry.
The condition of Mr Marios Gavriel (32), from London, was described yesterday as "out of danger but still serious" in hospital in Marbella. He was hit in the lungs and spleen by flying shrapnel in the first bomb attack in the Costa del Sol resort of Fuengirola as he was on his way to watch the England-Brazil World Cup match in a nearby cafe.
There were another two bombs on Friday - one in Marbella, 25 kms from Fuengirola, and one in an underground car park Zaragoza 650 kms away in which a security guard was slightly injured. There were two other attacks on Saturday; the Costa del Sol was a target again when a packet bomb exploded outside a hotel in Mijas, causing minor damage but no injuries, and a 50 kilogram car bomb was detonated in the centre of Santander on Saturday night causing considerable damage to buildings, but no injuries.
It is estimated that ETA used 170 kilograms of explosives in their five bombs this weekend, almost certainly part of the 1,600 kilograms stolen from a mining store in France last year.
Last week, police discovered a 131 kilograms of explosives, detonators and fuses in mountains near Valencia in a search which followed the arrest of a suspected ETA militant. They believed they had aborted a wave of planned bombing attacks. The interior minister's spokesman said the bombs had not upset the summit. "We should not over-estimate their performance. They were fairly easy targets, and in many ways are a sign of their weakness," he said.
