Iran’s state TV Sunday quoted spokesman Gholam Hossein Mohseni Ejehi announcing the arrests, which he said took place after the January attacks. He did not give further details.
It is unusual for Iran to publicly announce arrests following such incidents.
Protesters set fire to the Saudi embassy in Tehran and attacked its consulate in another Iranian city in response to the kingdom’s execution of a prominent Shiite cleric on Jan 2.
The protests provoked Saudi Arabia to cut diplomatic ties with Iran, escalating tensions between the longtime regional rivals.
