Iranian police have detained ten people suspected of links to a suicide car bomb attack in the port city of Chabahar, police chief Hossein Ashtari said.
"Good clues have been obtained and hopefully with the public’s cooperation ... we will get to the main leads," IRNA cited Ashtari as saying.
He added that more suspects have been identified and are being sought.
At least 48 people were also injured in Thursday’s suicide car bomb attack by a Sunni militant group on a police headquarters in the port city of Chabahar in southeast Iran, according to state media.
