United Nations Security Council resolution 816, adopted on 31 March 1993, after reaffirming resolutions 781 (1992), 786 (1992) concerning a ban on military flights over Bosnia and Herzegovina and recognising the current situation in the region, the council, acting under Chapter VII of the United Nations Charter, extended the ban to cover flights by all fixed-wing and rotary-wing aircraft over the country, and to use all measures necessary to ensure compliance with the ban.

[1] The council went on to note that this ban did not apply to flights destined for use by the United Nations Protection Force (UNPROFOR) or for humanitarian reasons.

It also urged member states to co-operate with UNPROFOR with measures they have taken to implement the current resolution and rules of engagement, and in the event of the co-chairmen of the Steering Committee of the International Conference on the Former Yugoslavia notifying the council that all the Bosnian parties have accepted their proposals on a settlement, the measures set forth in the present resolution will be subsumed into the measures for implementing that settlement.

[2] Resolution 816 was adopted by 14 votes to none, with one abstention from China, due to its reservations about the authorisation of the use of force.

[3] Based upon Resolution 816, NATO began Operation Deny Flight on 12 April 1993 to enforce the no-fly zone.
