What happened February 1994 AD in Bosnia and Herzegovina

On 5 February 1994, Sarajevo suffered its deadliest single attack of the entire siege with the first Markale massacre, when a 120 millimeter mortar shell landed in the centre of the crowded marketplace, killing 68 people and wounding another 144.

On 6 February, UN Secretary-General Boutros Boutros-Ghali formally requested NATO to confirm that future requests for air strikes would be carried out immediately.

On 9 February 1994, NATO authorized the Commander of Allied Forces Southern Europe (CINCSOUTH), US Admiral Jeremy Boorda, to launch air strikes—at the request of the UN—against artillery and mortar positions in or around Sarajevo determined by UNPROFOR to be responsible for attacks against civilian targets.

On 12 February, Sarajevo enjoyed its first casualty free day since April 1992.

The large-scale removal of Bosnian-Serb heavy weapons began on 17 February 1994.

NATO also issued an ultimatum to the Bosnian Serbs demanding the removal of heavy weapons around Sarajevo by midnight of 20–21 February, or they would face air strikes.

NATO became actively involved when its jets shot down four Serb aircraft over central Bosnia on 28 February 1994 for violating the UN no-fly zone.
