The Czechoslovak government held an emergency session, and loudly expressed its disagreement with the occupation. Many citizens joined in protests, and by September 1968 at least 72 people had died and hundreds more injured in the conflicts. In the brief time after the occupation, which had put an end to any hope that Prague Spring had created, about 100,000 people fled Czechoslovakia. Over the whole time of the occupation, more than 700,000 people, including significant part of Czechoslovak "intelligentsia" left. Communists responded by revoking Czechoslovakian citizenship of many of these refugees and banned them from returning to their homeland.
