Tacks thrown in the road near the foot of the Jaizkibel climb sparked a number of sudden punctures on stage 2 of the Tour de France, with between 15 and 20 riders forced to stop to change wheels or ride to the finish with a slow puncture or a tack stuck in their tyre.
It is unclear who threw the tacks on the road and why. There were no signs of a protest during the stage, with the cycling-mad Basque fans cheering the riders during the 208km haul from Vitoria to San Sebastian.
