Bombing at Moscow airport seen as terrorism [VIDEO]

A bombing at the busiest airport in Moscow that killed at least 31 and injured 130 is being called a terrorist attack by Russian officials.

“From the preliminary information we have, it was a terror attack,” Russian President Dmitry Medvedev said of Monday’s attack on the Domodedovo Airport in a televised briefing.

Medvedev also said that those responsible for the attack would be “tracked down and punished.”

All Moscow transportation services went on high alert following the attack. Israel canceled all flights to Moscow.

Israel’s Foreign Ministry said it was not sure whether any of the victims were Israeli.

In March 2010, two female Chechen suicide bombers blew themselves up in the metro system, killing 40. In 2004, two suicide bombers boarded separate planes at the same airport and blew themselves up in midair, killing all 90 people aboard the two flights.
