The blast occurred at 4:30 p.m. at the entrance of international flight arrivals of Domodedovo Airport. Russian Anti-Terrorist Committee said the explosion killed 35 people and wounded 152 people.
President Dmitry Medvedev called the bombing a terrorist attack and increased security at all airports and transportation hubs.
Russian authorities said the explosion was a result of a suicide bomber who detonated a homemade bomb. The bomb was stuffed with small metal objects making it more deadly. The bomber activated the device in a crowded area where people were waiting for arriving flights.
An airport employee said Domodedovo Airport is functioning normally except incoming international flights are being routed through the domestic terminal, located on the other end of the airport.
