Yussef al-Shihri

After his death, the Saudi Gazette reported that two of his brothers, Faisal and Mustafa, and a cousin, Abdul Ghani Al-Shehri were imprisoned in at the Hai’er Prison on suspicion of terrorism.

Saudi security officials reported on the arrest of 113 suspects in March 2010. The arrest of 101 of those individuals were reported to have started with the interrogation of al-Shiri's surviving companion.

An October 2009 article in the Saudi Gazette asserts his older brother Saad Muhammad Al-Shehri took him to Afghanistan after he finished "intermediate school". Yussef Al-Shehri passed through the Saudi militant rehabilitation program following his repatriation from Guantanamo. He was named on Saudi Arabia's list of most wanted terrorist suspects on February 3, 2009. He was killed in a shootout with Saudi police, while apparently preparing to commit a suicide attack wearing an explosive belt on October 18, 2009.

Yusuf al-Shihri, his brother-in-law Said al-Shihri, and a sixteen-year-old cousin, Abdullah al-Shihri, were named on a Saudi most wanted list on February 3, 2009.

On November 25, 2008, the Department of Defense published a list of when captives left Guantanamo. According to that list he was repatriated to Saudi custody on November 9, 2007, with thirteen other men. The records published from the captives' annual Administrative Reviews show his repatriation was not the outcome of the formal internal review procedures. The records show his detention was not reviewed in 2007.

Peter Taylor writing for the BBC News called the Saudis repatriated on November 9, 2007, with al-Shihri, "batch 10". He wrote that the BBC's research had found this batch to be a problematic cohort, and that four other men from this batch were named on the Saudi most wanted list.

A Summary of Evidence memo was prepared for Yusef M Modaray's second annual Administrative Review Board, on October 12, 2006. The memo listed factors for and against his continued detention.

On June 15, 2005, human rights lawyer Clive Stafford Smith identified al-Shihri as one of a dozen teenage boys held in the adult portion of the prison. According to Smith, al-Shihri was 13 years old when captured. Smith observed that official US documents referred to this dozen minors solely by their initials, because US law prohibits identifying minors. Official documents referred to Al Shihri as "YAS".

After another former Saudi captive, Sa'id Ali Jabir Al Khathim Al Shihri, appeared in internet videos that threatened further attacks, an article in the Saudi Gazette reported that he had a brother-in-law, named "Yusuf al-Shihri", who was also a former Guantanamo captive. Said Ali Al Shihri married Yussef Al Shiri's sister after their repatriation from Guantanamo. Yussef's sister had two previous husbands. In a child custody dispute her first husband sought custody claiming the sister was a takfiri. He claimed her second husband had also been a militant, and that he was killed in a shootout with security officials in 2004.

At the age of sixteen, he was captured along with his older cousin as part of a large group of 120 soldiers near Kunduz, and transferred to Shiberghan prison for six weeks, before being flown to Guantanamo on January 16, 2002.

Yussef Mohammed Mubarak al-Shihri (1985–2009) was a citizen of Saudi Arabia who was held in extrajudicial detention in the United States's Guantanamo Bay detention camps, in Cuba. He was born on September 8, 1985, in Riyadh Saudi Arabia.
