An Iranian ethnic Arab separatist Sunni militant group and Islamic State both claimed responsibility for that attack.
A suicide auto bombing followed by an armed assault killed at least two people and wounded many more outside police headquarters in the port city of Chabahar in restive southeastern Iran on Thursday.
"Terrorists attacked the police post in Chabahar with an explosives-laden vehicle", he said.
"The terrorists exploded a vehicle carrying explosives at the gate of the [police] headquarters", Bameri was quoted as saying by the official government news agency IRNA.
Mohammad Hadi Marashi, deputy governor for security affairs, told state TV that two police officers were killed in the attack.
Ansar al-Furqan, a Sunni jihadi group, clamed credit for the attack.
TV also reported shooting in the area, which is located in the mainly Sunni province of Sistan-Baluchestan that has always been plagued by unrest from both drug smuggling gangs and separatist militants.
