When Barack Obama took office, he banned torture, shut down the CIA's network of black-site prisons and pledged to close Guantanamo. But exactly where terror suspects should go continues to be a legal and political challenge for the administration. So we've rounded up some of the best reporting on rendition and detention under Obama. Got others? Add them in the comments.

In a secret prison in Baghdad, hundreds of Sunnis were allegedly held and tortured under the jurisdiction of Iraqi prime minister Nouri Maliki's military office.

Several individuals who were detained overseas and held by local security forces under harsh conditions allege U.S. officials were complicit in their arrests. This April, Mother Jones wrote about a Muslim American man who claims he was interrogated and beaten by local police in the United Arab Emirates. He claims the questions were "eerily similar" to those asked by American officials when he was earlier interrogated in Sudan. In March 2010, The Nation chronicled the experience of a Lebanese man and naturalized U.S. citizen questioned by U.A.E. officials in the suspected presence of an American interrogator. In January 2011, the New York Times reported on a Somali-American teenager who claims he was held in a Kuwaiti detention cell and interrogated about contacts with terrorist suspects in Yemen. He said he was visited by American officials while in detention. In each case, the U.S. has declined comment.
