What happened April 1992 AD in Bosnia and Herzegovina

The Bijeljina Killings (of mostly Bosniaks) on 1–2 April.

On 3 April, the Battle of Kupres began between the JNA and a combined HV-HVO force that ended in a JNA victory.

On 6 April Serb forces began shelling Sarajevo, and in the next two days crossed the Drina from Serbia proper and besieged Muslim-majority Zvornik, Višegrad and Foča.

"full-scale hostilities had broken out by 6 April", the same day that the United States and European Economic Community (EEC) recognized Bosnia and Herzegovina.

On 23 April, the JNA evacuated its personnel by helicopters from the barracks in Čapljina, which was under blockade since 4 March.

On 27 April, the Bosnian government ordered the JNA to be put under civilian control or expelled, which was followed by a series of conflicts in early May between the two.

Prijedor was taken over by Serbs on 30 April.
