Among those sentenced are Omar Ayub Khan, Zartaj Gul, Murad Saeed, Shibli Faraz, Hammad Azhar, Kanwal Shauzab, Sheikh Rashid Shafiq, Shehbaz Gill, Zulfi Bukhari, Muhammad Ahmad Chattha, Rai Hassan Nawaz and Rai Muhammad Murtaza.
The verdict was announced by an Anti-Terrorism Court in Rawalpindi, which declared the accused proclaimed offenders in the case.
The charges relate to the violent protests that erupted on May 9, 2023, after the arrest of PTI founder and former prime minister Imran Khan.
During the unrest, protesters attacked several government and military installations, including the General Headquarters (GHQ) in Rawalpindi.
Authorities stated that public and military property was damaged and some sites were set on fire during the protests.
