Pakistan has declared the Zainabion militia, an Iranian proxy, affiliated with the Revolutionary Guards as a terrorist organization. 

The Zainabion (named after Zaynab daughter of Ali and Fatima, daughter of Muhammad), are a Pakistani Shia militia that also operates in Syria, under the command and guidance of Iran. 

At first the militia was entrusted with the protection of the Sayyida Zaynab mosque and other Shiite holy sites in Syria. The majority of the militia's fighters are made up of Pakistani Shias from the country's Shia community or Pakistani Shias living in Iran.
