Despite these attempts, tensions steadily increased throughout the second half of 1992. An armed conflict occurred in Busovača in early May and another one on 13 June. On 19 June, a conflict between the units of the TO on one side, and HVO and HOS units on the other side broke out in Novi Travnik. Incidents were also recorded in Konjic in July, and in Kiseljak and the Croat settlement of Stup in Sarajevo during August. On 14 September, the Constitutional Court of Bosnia and Herzegovina declared the proclamation of Herzeg-Bosnia unconstitutional.
