1993 saw no major changes in the front lines against Serbs. Instead, this year marked the start of the Croat–Bosniak War in Central Bosnia and in Herzegovina, notably the Mostar region. Pressured and contained by heavily armed Serb forces in Bosnia-Hercegovina and Croatia, the ethnic Croat militia forces – the Croatian Defence Council (HVO) – shifted their focus from defending their parts of Bosnia from Serbs to trying to capture remaining territory held by the Bosnian Army. It is widely believed that this was due to the 1991 Milošević–Tuđman Karađorđevo meeting where presidents Slobodan Milošević and Franjo Tuđman discussed partitioning Bosnia between Croatia and Serbia. In order to accomplish this, the Croatian forces would have to defeat the Bosnian Army, since the territory that they wanted was under Bosnian government control. The HVO with great engagement from the military of the Republic of Croatia and material support from Serbs, attacked Bosniak civilian population in Herzegovina and in central Bosnia starting an ethnic cleansing of Bosniak populated territories, such as in the Lašva Valley ethnic cleansing.
