LISBON, Portugal – Truckers in Canada have it rough when it comes to fuel prices, but at least we haven’t yet started killing each other over the problem.

According to media reports in Europe, two truck drivers are dead after clashes during violent protests over soaring fuel prices.

The protests – the result of a strike that began Monday – are taking place at Spanish, French and Portuguese borders, effectively disrupting the flow of goods between those countries.

The first driver was killed in southern Spain when he was run over by a van trying to drive through a picket line.

A similar incident north of Lisbon, Portugal, left a 52-year-old man dead when he was struck at a Portuguese roadblock.

According to Manual Agostinho – a fellow striker who was running the roadblock – a heavy goods truck failed to heed signals to stop at the roadblock and ran over the victim.

"It went over him. It's murder," Agostinho told Portuguese news agency Lusa. The truck had been traveling at about 50 kilometers an hour (30 miles an hour), he added.

Police officers at the scene -- about 100 kilometers (60 miles) from the Portuguese capital -- arrested the driver of the truck immediately, he said.
