In Ipar Euskal Herria, a huge police operation was launched against Basque refugees. During the operation, which started at 6:00 in the morning and lasted throughout the day, nearly 2,000 policemen arrested 61 people. In a few days, 200 Basques were arrested, 60 of them were expelled and 15 deportees. Many detainees held by the Spanish Police on the border of Irun subsequently reported torture. At the afternoon demonstration in Biarritz to denounce the event, the police rebelled strongly against the citizens.

Amnesty International stated that those delivered were in danger of being tortured.
