Europeans authorities have tightened security at airports and on city streets after deadly attacks on the Brussels airport and its subway system.
The Paris airport authority said security was tightened at all Paris airports soon after the Brussels explosions on Tuesday morning. Airports in London, Prague, Amsterdam and Bucharest, Romania, also saw increased security.
The attacks come just days after the main suspect in the Nov. 13 Paris terror attacks was arrested in Brussels on Friday.
The British and Polish governments convened emergency meetings as they beefed up security at airports.
Austrian Interior Ministry spokesman Karl-Heinz Grundboeck said more police are on the streets and at airports in Vienna and other major Austrian cities even though there appears to be no “Austria connection.”
Danish police said they had increased patrols at the Copenhagen airport and other key points in the city following the deadly explosions.
“We are aware of what has happened in Brussels. Therefore you will see more police in the airport and at key points in Copenhagen,” Danish police said on its official social media page.
Danish authorities have been on high alert since two people were killed in shooting attacks at a free speech event and a shul in Copenhagen in February last year.
Police in Sweden said they had reinforced their presence at airports and taken increased security measures at other public places. Finnish Interior Minister Petteri Orpo said “Finnish security officials have increased monitoring at Helsinki-Vantaa airport.”
