U izvještaju se kaže da je operacija izvedena nakon što je jedan osumnjičeni, za koga se vjeruje da je bio u inostranstvu na obuci za specijalna oružja i eksplozive, bio pod prismotrom pola godine.
The report suggested the operation was carried out after one suspect, believed to have undergone special weapons and explosives training abroad, was under surveillance for half a year.
