MOSCOW (AP) - Russian officials say an explosion caused by an apparent terrorist attack ripped through the international arrivals hall at Moscow's busiest airport, killing 31 people and wounding about 130.
President Dmitry Medvedev told officials "from the preliminary information we have it was a terror attack,"
The state RIA Novosti news agency, citing sources in law enforcement, said the explosion Monday afternoon at Domodedovo Airport may have been caused by a suicide bomber.
The airport is generally regarded as Moscow's most up-to-date, but its security procedures have been called into question.
In 2004, two suicide bombers were able to board planes at the airport by buying tickets illegally from airport personnel. The bombers blew themselves up in midair, killing all 90 people aboard the two flights.
