List of emergency special sessions of the United Nations General Assembly
An emergency special session is an unscheduled meeting of the United Nations General Assembly to make urgent recommendations on a particular issue. They are typically rare — a fact reflected in there being only 10 in the history of the United Nations. Most emergency special sessions run for a single "meeting", which itself can run over a number of days — the Tenth, however, is the only emergency special session to be resumed more than once (the Seventh emergency special session of the United Nations General Assembly was resumed once), meaning that that Session has spanned across a number of "meetings".
The UN General Assembly's 'Uniting for Peace' resolution (A/RES/377 A) demands a majority—procedural—vote of the Security Council, or a request by a majority of UN Member states being received by the Secretary-General, for the convocation of an emergency special session, within 24 hours.
