A Cuban-operated airliner with at least 110 people on board crashed into a cassava field just after takeoff from Havana's international airport on Friday. There appeared to be mass casualties as Cuban officials said three people had survived, but had yet to give an official toll. Authorities said there were 104 passengers and nine foreign crew members on the flight that was headed to the eastern city of Holguin. Witnesses said they saw a thick column of smoke near the airport. Authorities are still gathering information about the crash and cannot confirm if Americans were on the flight or not, a U.S. State Department official said Friday.
