Azizollah Maleki, the police chief in Hormozgan Province, where the terrorists were killed during a firefight with security forces, made the remarks to reporters on Monday.
"Intelligence work and the monitoring of current news about movements by a group of armed terrorists in the east of Hormozgan had the issue placed on the police’s special agenda,” he said.
Police forces took further operational and intelligence measures, tracking the group’s movements and identifying the places frequented by them.
They confronted the foursome in a mountainous terrain near the province’s Roudan Country, Maleki said, adding that an armed conflict ensued, which resulted in the deaths of the terrorists.
"Two of the terrorists were foreigners bearing foreign ID cards. The identity of the rest is being investigated,” Maleki said.
The terrorists had four military weapons, 112 live bullets, some explosives, and a Daesh flag in their possession.
All the attackers were killed during engagement with security forces. Other elements have also been arrested in connection with the massacre.
Senior MP Akbar Ranjbarzadeh said on Sunday that a number of the elements behind the incident, which had fled the country were also exterminated.
