US President Barack Obama suggested that the cause of the crash of the Russian Airbus A321 in the Sinai Peninsula could be a terrorist attack. According to Obama, "there is a possibility that there was a bomb on board."
Andrei Manoilo, professor of the Moscow State University:
"When it is the president of such a great power as the United States of America that starts spreading rumors, it only shows how sick the American society is, if they gossip on the state level, and it is a blabber, who takes the top position in the country. Responsible individuals, who carry responsibility for their words and actions, as well as for the words and actions of other people, would not say such a thing."
