The civilians were sentenced by a Pakistani military court to periods of two to 10 years in a ruling that underscored concerns among Khan’s supporters that military courts will play a bigger role in cases related to the former leader.

Washington “is deeply concerned that Pakistani civilians have been sentenced by a military tribunal for their involvement in protests on May 9, 2023,” the U.S. State Department, opens new tab said.

The British government’s foreign office, opens new tab added that “trying civilians in military courts lacks transparency, independent scrutiny and undermines the right to a fair trial.”

The European Union said the sentences were “inconsistent with the obligations that Pakistan has undertaken under the International Covenant on Civil and Political Rights.”

Khan supporters attacked military installations to protest his arrest by paramilitary soldiers.

The ruling on Saturday came days after Khan was indicted by an anti-terrorism court. After his arrest in May 2023, Khan was briefly released before being arrested again in August that year and he has since been in jail.

He has faced dozens of cases since he was removed as prime minister in 2022, after which he launched a protest movement against a coalition of his rivals led by current Prime Minister Shehbaz Sharif.

Khan says cases against him, which disqualified him from contesting the 2024 elections, are politically motivated. He had a fallout with Pakistan’s military that he blames for his ouster.

Candidates whom Khan backed secured the highest number of seats in the elections. However, his rivals formed a coalition government. A U.N. human rights working group has said Khan’s detention violates international law.
