Polish Prime Minister Donald Tusk says that shortly after midnight the Polish border guard reported suspicious activity along the Polish-Russian border. Polish forces were mobilized immediately, and successfully prevented an attempted provocation, Tusk said. He added that Poland received intelligence from its services and its allies warning of possible sabotage and provocations along the border in the first half of November. Significant police, border guard and counter-terrorism forces have been deployed over the past few days in response. —. GeoInsider.
