The number of civilian casualties in Operation Storm is disputed. The State Attorney's Office of the Republic of Croatia claims that 214 civilians were killed—156 in 24 instances of war crimes and another 47 as victims of murder—during the battle and in its immediate aftermath. The Croatian Helsinki Committee disputes the claim and reports that 677 civilians were killed during the same period. When submitted as evidence, their report was rejected by the ICTY due to unsourced statements and double entries contained within. Serbian sources quote 1,192 civilians dead or missing. ICTY prosecutors set the number of civilian deaths at 324. Croatian government officials estimate that 42 Croatian civilians were killed during the operation.
