In June 1992, the focus switched to Novi Travnik where Croat efforts to gain control were met with resistance. On 18 June 1992 the Bosnian government forces in Novi Travnik received an ultimatum from the HVO which included demands to abolish existing government institutions, pledge allegiance to a newly established Croat authority, subordinate Bosnian forces to the HVO and expel Bosniak refugees – all within 24 hours. On 19 June 1992 armed conflict broke out. The fighting lasted two hours and the headquarters of the Bosnian Territorial Defence, the elementary school and the post office were attacked and damaged by local Croat units, including units from Vitez and Busovača. Bosniaks in the lower part of the town were subjected to killings, rape and other mistreatment.
