Bahraini authorities on May 7 arrested prominent human rights activist Nabeel Rajab, according to the country's Interior Ministry. According to his lawyer, Rajab was arrested for messages he posted on Twitter criticizing the Interior Ministry. Rajab is the president of the Bahrain Center for Human Rights (BCHR), a group that has been critical of the Bahraini regime's response to protests and demonstrations in Bahrain which have been ongoing since February 2011. Following Rajab's arrest, the BCHR expressed concern that "[t]he authorities in Bahrain have used many methods in attempting to prevent and/or limit human rights defenders in Bahrain from carrying out their work of documenting and reporting on human rights violations in the country." Rajab was charged with insulting a statutory body and will be detained for seven days.

Ali Mussa Daqduq, a former detainee of the US with ties to Hezbollah, was cleared of all charges in an Iraqi court, his lawyer said May 7. The US handed Daqduq over to Iraqi authorities in December as part of the "end of the Iraq War." US President Barack Obama considered trying Daqduq on US soil but was unable to come to an agreement with Iraqi officials. Since no decision could be reached, Duqdaq had to be transferred to Iraq officials pursuant to the 2008 Status of Forces Agreement between the US and Baghdad. Many politicians expressed concern at the time of his transfer that Iraqi courts would not be able to convict Duqdaq. The US government did not immediately respond the dismissal of charges.

The US Court of Appeals for the Ninth Circuit on May 2 granted qualified immunity to former Bush administration official John Yoo over allegations of wrongdoing in relation to controversial memos asserting the legality of "enhanced interrogation techniques." The lawsuit, brought by convicted terrorism defendant Jose Padilla, claimed Yoo's legal opinions endorsing "enhanced interrogation techniques" led to Padilla being tortured. Padilla, a US citizen currently serving a 17-year sentence on terrorism-related charges, said that he was tortured while held as an "enemy combatant" in military custody in a Navy military brig in Charleston, SC. In granting qualified immunity, the panel wrote:

The Mexican Chamber of Deputies on April 30 approved a bill that will recognize, protect and provide aid to victims of crimes stemming from the gang-related drug wars that have engulfed the country for nearly the last six years. Known as the General Victims Act, the law was passed by Mexico's lower house of Congress as a means to compensate those persons adversely affected by fighting between gangs and security forces. The law will provide financial, legal and medical aid to those in need; victims of criminal violence will be eligible for relief of up to 950,000 pesos ($73,000). The bill was passed by the Mexican Senate last week in response to longstanding demand, as more than 47,500 people have died in Mexico over the last five-and-a-half years due to drug-related violence, and thousands more have gone missing.

UN Special Rapporteur on Rights of Indigenous Peoples James Anaya will visit the United States from April 23 to May 4 to launch the UN's first ever investigation into the rights situation of Native Americans. Anaya will be looking into the rights of Native Americans, Alaska Natives and Native Hawaiians, and meeting with government officials throughout the nation. One main goal of his investigation is to determine how the Unites States' endorsement of the UN Declaration on the Rights of Indigenous Peoples in December 2010 has affected the rights of these groups, and what improvements may still be needed. Anaya will report his findings and make recommendations to US federal and state officials during his trip.

The Pentagon announced on April 19 that two Uighur detainees were released from the US detention center at Guantánamo Bay to be transferred to El Salvador, where they have chosen to resettle. They are being released pursuant to a 2008 order by the US District Court for the District of Columbia. An executive order issued in 2009 mandated review of the cases by the Interagency Guantánamo Review Task Force (IGRTF), and all six agencies on the force gave consent to release the two detainees. The US said it has worked with El Salvador's government to ensure that the two men arrive safely and are not harmed upon arrival, as well as to protect them against inhumane treatment at any stage of the transfer.
