Authorities in Ukraine and the Czech Republic were beefing up airport security measures in the wake of the suicide attack in Moscow. Police with sniffer dogs were randomly checking passengers and their luggage for possible explosives. Britain’s Department of Transport, responsible for Europe’s busiest airport, London’s Heathrow, declined to comment on any possible new airport measures, although such arrangements are kept under constant review. Security experts have warned is impossible to screen the crowds at arrival terminals because many airports have been turned into commercial centers, with shops, food courts, train stations and other facilities. The attack at Domodedovo’s international arrival areas killed 35 people and wounded 180.

Domodedovo Airport closed down temporarily after the blast but then reopened after only 20 minutes. Many aircrews and passengers in its secure departure and arrival areas at the time were not even aware of the blast.

What happened at Domodedovo shows that the airport lacks security.
