Around one hundred and thirty others have been hurt by the blast in the international arrivals hall, a low security area often filled with waiting family members and taxi drivers. Police suspect a suicide bomber is to blame, and they are working to identify him and find out how he was able to get into the airport. Investigators are also currently looking for three people who they believe could be linked to the explosion. Russian President Dmitri Medvedev has ordered extra security to be put in place in all of Moscow's airports and railway stations. Despite the chaos, planes are continuing to land and take off at Domodedovo airport.
