[JURIST] Lawyers for detainees being held at Guantanamo [JURIST news archives] say as many as six of those being held were captured before they turned 18 [NYT report]. One lawyer says his client was not even 15 when captured, and was physically abused. According to the military, only three juveniles have been held at the terror detention facility, and they were released in January 2004. Amnesty International had previously urged their release [AP report, AI press release] and Human Rights Watch had written to US Secretary of State Donald Rumsfeld [HRW letter] urging the United States to strictly observe international children's rights standards regarding the detainees. Also still being held is Omar Khadr, a Canadian who was 17 when sent to Guantanamo in September 2004, who the military said admitted to being a terrorist [CBC News report] and is accused of killing an American soldier with a grenade [CBC News report]. Two problems cloud the issue of detaining minors: the military defines juveniles as those under 16 instead of 18, and military officials cannot always be certain how old a detainee is.
