On 3 April 1993, the Croat leadership met in Mostar to discuss the implementation of the Vance-Owen Peace Plan. The Croats decided to implement the creation of "Croatian Provinces" (Provinces 3, 8 and 10) placing the Bosnian armed forces under the command of the General Staff of the HVO. On 4 April, according to Reuters, the HVO HQ in Mostar set a deadline for President Izetbegović to sign the above agreement and stated: "If Izetbegović fails to sign this agreement by 15 April, the HVO will unilaterally enforce its jurisdiction in cantons three, eight and ten." In a message from Kordić, Ignac Koštroman and Anto Valenta, the Croat people were told to display more Croatian flags on buildings.
