Beijing (CNN) -- Relatives of vanished Malaysia Airlines Flight 370 passengers wailed and yelled in a Beijing hotel Thursday as the airline announced it was closing the assistance centers where they'd been gathered for weeks -- effectively telling the families to go home. The closures also will mean no more mass daily briefings for the relatives -- news that sparked a new wave of anguish and despair for the hundreds who heard it at Beijing's Lido Hotel. "What can we do?" a relative yelled, as others kneeled in front of police who had assembled in the hotel briefing room to keep order.
