From The Guardian:
A former Guantanamo Bay inmate who was incarcerated there between 2002 and 2009 was killed in a US airstrike in Yemen. He was not considered a high-value target.
Also killed in the same airstrike in Abyan governorate was Usayd al-Adnani who was considered to be an explosives expert.
These airstrikes have not been conducted based on intelligence gathered from the January raid.
