On 7 June the Croatian Army (HV) launched an offensive code named Operation Jackal, the objective of which was to relieve Mostar and break the JNA siege of Dubrovnik. The offensive was supported by the HVO, which attacked the Army of Republika Srpska (VRS) positions around Mostar. By 12 June the HVO secured the western part of the city and by 21 June the VRS was completely pushed out from the eastern part. Numerous religious buildings and most of the city's bridges were destroyed or severely damaged during the fighting. Among them were the Catholic Cathedral of Mary, Mother of the Church, the Franciscan Church and Monastery, the Bishop's Palace and 12 out of 14 mosques in the city. After the VRS was pushed from the city, the Serbian Orthodox Žitomislić Monastery and the Cathedral of the Holy Trinity were demolished.
