Iran says it has killed mastermind of twin attacks
Iran says it has killed the alleged mastermind of twin attacks last week claimed by the Islamic State group.
The official IRNA news agency on Sunday quoted intelligence minister Mahmoud Alavi as saying the suspect left Iran for a neighbouring country after the attacks, but "was sent to hell" by Iranian intelligence agents and " fellow intelligence services".
Mr Alavi did not provide further details or offer any evidence.
Five attackers stormed Iran's parliament and a shrine to revolutionary leader Ayatollah Ruhollah Khomeini in Tehran on Wednesday, setting off clashes with security forces and killing at least 17 people.
Iran says the attackers, who were all killed, had fought for the IS group in Syria and neighbouring Iraq. It says dozens of people have been detained.
