An explosion set off by a suicide bomber ripped through Moscow's busiest airport Monday, killing at least 35 people and wounding 180 others.

The attack took place mid-afternoon in the international arrivals terminal at Domodedovo Airport. Authorities said the airport has had security problems in the past.

President Dmitry Medvedev called the event a terrorist attack and immediately called for increased security at Moscow's other airports and transport facilities.

No one immediately took responsibility for the explosion, but Chechen separatists have claimed responsibility for previous terror attacks in Moscow, including a subway bombing in March 2010 that killed 40.

The latest attack on the Russian capital is now drawing questions of the country's ability to safely host major international sports events like the 2014 Winter Olympics in Sochi and the 2018 World Cup.
