Pakistan has sentenced to prison 108 members of jailed ex-Prime Minister Imran Khan's party, for their involvement in protests against the military in 2023.

Violent protests erupted nationwide in May 2023 after security forces arrested Khan during his court appearance on corruption charges.

Authorities have already handed down dozens of sentences in the last two years, but Thursday's convictions - which include a 10-year term for opposition leader Omar Ayub Khan - deal a major blow to Khan's Pakistan Tehreek-e-Insaf (PTI) party.

Opposition figures have denounced the rulings by the anti-terrorism court, which also disqualified six PTI lawmakers from their seats.

"For the first time in Pakistan's judicial history, such a sad and shameful incident occurred that the leaders of the opposition in both houses [of parliament] were punished solely on the basis that they were loyal allies of Imran Khan's political narrative, public representation, and constitutional struggle," PTI wrote on X.
