Alleged terrorists without a trial.
I do not know the process in USA for branding individuals as Specially Designated Global Terrorist (SDGT), but this is what Google AI says about it:
Question: Have Masood Azhar and Hafiz Saeed designated as Global terrorists by USA?
Yes, the United States has designated both Masood Azhar and Hafiz Saeed as Specially Designated Global Terrorists (SDGTs). They have also both been designated as terrorists by the United Nations.
Masood Azhar
Founder and leader: Azhar is the founder and leader of the Pakistan-based militant group Jaish-e-Mohammed (JeM).
U.S. designation: The U.S. Department of the Treasury officially designated Masood Azhar as an SDGT in 2010.
UN designation: After years of attempts blocked by China, the UN Security Council.
Notable attacks: Azhar and his group are responsible for numerous attacks in India, including the 2001 attack on the Indian Parliament and the 2019 Pulwama attack.
Hafiz Saeed
Co-founder and leader: Saeed co-founded Lashkar-e-Taiba (LeT), the militant organization responsible for the 2008 Mumbai attacks. He is also the leader of its front organization, Jamaat-ud-Dawa (JuD).
U.S. designation: The U.S. designated Saeed as an SDGT in May 2008, and placed a $10 million bounty on his head in 2012 for his role in the Mumbai attacks.
UN designation: Saeed was designated by the UN under UNSCR 1267 in December 2008, following the Mumbai attacks.
Status in Pakistan: Despite international designations, Saeed was released from house arrest in Pakistan multiple times, which drew strong condemnation from the U.S.. He has, however, been convicted of terror financing charges by Pakistani Courts.
