Iran says it has killed the alleged mastermind of twin attacks last week claimed by the Daesh group.

The official IRNA news agency on Sunday quotes Intelligence Minister Mahmoud Alavi as saying the suspect left Iran for a neighbouring country following the attacks but "was sent to hell" by Iranian intelligence agents and " fellow intelligence services." 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 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 Daesh group in Syria and neighbouring Iraq. It says dozens of people have been detained.
