UN Secretary-General Ban Ki-Moon announced on March 21 that the UN will initiate a probe into the possible use of chemical weapons in Syria. The Syrian government requested the probe earlier this week after anti-government forces carried out an attack on a village near Aleppo. Ban declared that the investigation will involve other international bodies such as the World Health Organization and the Organization for the Prohibition of Chemical Weapons. In his remarks, Ban stated that any use of chemical weapons would be a serious crime and that the Syrian government has the primary responsibility of ensuring the security of chemical weapons. Ban said that the investigation would start as soon as possible.

Congolese war crimes suspect Gen. Bosco Ntaganda surrendered himself to a US embassy in Rwanda on March 18 and requested extradition to the  International Criminal Court  (ICC). Ntaganda has been wanted by the ICC since 2006 on charges enlisting and conscripting children under the age of 15 and of using them to participate actively in hostilities in the Democratic Republic of Congo (DRC) from July 2002 to December 2003. Ntaganda remained at large, however, and in 2012 ICC Pre-Trial Chamber II issued a second warrant for Ntaganda's arrest for additional war crimes and crimes against humanity in contravention of the Rome Statute:

Ahmed Qaddaf al-Dam, cousin of Moammar Qaddafi, was arrested at his home March 19 in central Cairo by Libyan forces. The arrest of Qaddaf al-Dam coincides with the second anniversary start of the air campaign in Libya by the North Atlantic Treaty Organization (NATO) that assisted rebels in toppling Qaddafi's regime. Qaddaf al-Dam, who is said to have beeb a trusted accomplice of the former leader, has said he plans on filing a complaint with the Egyptian public prosecutor and Libyan authorities. The Egyptian-controlled Middle East News Agency (MENA) reported that Libyan authorities will gain control of al-Dam and plan on prosecuting him. The specific charges faced by Qaddaf al-Dam are still unknown.

A criminal court in Riyadh on March 9 sentenced two Saudi Arabian human rights activists to at least 10 years in prison. The activists were found guilty earlier that day of sedition, providing foreign media with inaccurate information, founding and operating an unlicensed human rights organization and other criminal offenses. Mohammed al-Qahtani and Abdullah al-Hamid founded the Saudi Civil and Political Rights Association, a group that documented human rights abuses, and the group has been ordered to disband. Al-Qahtani was sentenced to 10 years in prison and received a 10-year travel ban. Al-Hamid was sentenced to five years in prison, ordered to serve six years of a sentence from which he he had previously been pardoned, and received a five-year travel ban. The Arabic Network for Human Rights Information (ANHRI) has demanded the immediate release of the activists. Both men will remain in detention until a ruling on their appeal next month.

UNICEF on March 6 reported (PDF) that Israeli practices concerning the detention of children may violate international legal standards. The report claims approximately 700 Palestinian children are detained every year in Israeli military facilities. Further, UNICEF suggests mistreatment of these children in these facilities is "widespread, systematic and institutionalized." According to the report, the mistreatment includes:

Defense lawyers for detainees held at Guantánamo Bay and the Center for Constitutional Rights (CCR) sent a letter (PDF) to Rear Admiral John Smith Jr.  describing harsh conditions faced by the detainees and indicated that the detainees have begun to protest the conditions, including participating in a hunger strike. The letter alleged that "camp authorities have been confiscating detainees' personal items, including blankets, sheets, towels, mats, razors, toothbrushes, books, family photos, religious CDs, and letters, including legal mail; and restricting their exercise, seemingly without provocation or cause."

The US Court of Appeals for the District of Columbia Circuit on Feb. 1 upheld the listing of polar bears as a "threatened" species under the Endangered Species Act (ESA). Designation of the animal as threatened gives polar bears the lower of two levels of protection. This designation was challenged by both environmental groups, which argued that the polar bears should be considered endangered and be given the highest level of protections, and industry and sporting groups, which argued that they should not be protected under the act at all. The court determined that the Fish and Wildlife Service (FWS) used "reasoned decisionmaking" in deciding to list polar bears as threatened, and therefore did not disturb its designation. The agency went through a three-year rulemaking process and determined that, due to the effects of global warming, polar bears are likely to become an endangered species in the foreseeable future, warranting their designation as threatened.

The United Arab Emirates (UAE) on March 4 began the trial of 94 people charged with plotting to overthrow the government. The group of defendants includes unnamed doctors, academics, lawyers and other professionals arrested over the past year and accused of forming a secret network with ties to the Muslim Brotherhood and designs to raise money in a plotted coup against the UAE's ruling families. International human rights groups such as Amnesty International and Human Rights Watch have criticized the charges and raised concerns regarding the transparency and fairness of the trial. Most of the defendants are members of the conservative Reform and Social Guidance Association (al-Islah), a nonviolent Islamist political association.
