Security forces in Egypt arrested 516 supporters of the banned Muslim Brotherhood, Interior Minister Mohamed Ibrahim announced Jan. 26. The previous day, which marked the fourth anniversary of the 2011 uprising and the fall of Hosni Mubarak, supporters of the Brotherhood and ousted president Mohamed Morsi battled with security forces while rallying against President Abdel Fattah al-Sisi's government. Twenty people were killed during the demonstrations in addition to the 516 arrested. Ibrahim stated, "We confirmed, beyond the shadow of a doubt, that all those who took to the streets yesterday were Muslim Brotherhood elements alone. ... We arrested 516 elements from the Muslim Brotherhood group who were involved in firing ammunition, planting explosives and bombing some facilities." The arrests were the largest police sweep of Morsi supporters since Sisi took office in May.

Egypt's Court of Cassation upheld convictions and three-year prison sentences of three activists Jan. 26 for violating the country's protest laws. Ahmed Maher, Ahmed Douma and Mohammed Adel were arrested under a law that bans political gatherings of more than 10 people without prior government permission. As the Court of Cassation is Egypt's highest, the convicted men have no further legal redress. Human Rights Watch has criticized the law since its drafting, claiming that it goes "well beyond the limitations permitted under international law" for the right to peacefully assemble. The UN Office of the High Commissioner for Human Rights also condemned the law, its spokesperson stating that "no one should be criminalized or subjected to any threats or acts of violence, harassment or persecution for addressing human rights issues through peaceful protests." Thousands have been arrested under this law, including many supporters of the Muslim Brotherhood.

Former Lord's Resistance Army (LRA) commander Dominic Ongwen on Jan. 26 made his first appearance  before the International Criminal Court (ICC). The pre-trial hearing was brief as Ongwen simply had to confirm his identity and that he clearly understood the charges against him. During his hearing, Ongwen thanked God and referred to himself as a former soldier saying that he "was abducted in 1988 and...taken to the bush when [he] was 14 years old." He spoke in Acholi, his native language. Ongwen faces three counts of crimes against humanity: murder, enslavement, and inhumane acts of inflicting serious bodily injury and suffering; and four counts of war crimes: murder, cruel treatment of civilians, intentionally directing an attack against a civilian population, and pillaging. A pre-trial confirmation of charges hearing has been scheduled for August. This hearing will determine whether there is sufficient evidence to establish substantial grounds to believe that Ongwen committed each of the crimes with which he is charged. The ICC took legal custody of Ongwen in Central African Republic's capital Bangui earlier this month.

Egypt's Court of Cassation on Jan. 22 ordered a retrial for four police officers facing accusations of involuntary manslaughter relating to the deaths of 37 prisoners  in a van outside the Abu Zaabal prison in 2013. The prisoners, arrested days before during protests in support of former president Mohamed Morsi, were being transported from the Nasser City police station to the Abu Zaabal prison on Aug. 18, 2013, when the officers in question allegedly fired tear gas into an overcrowded police van. The gas caused 37 of the 45 prisoners within the van to die from suffocation. A series of conflicting early reports asserted that the detainees were attempting to escape, or being freed by an armed group. In March one of the officers, Lt. Col. Amr Farouk, was sentenced to 10 years in prison for involuntary manslaughter and extreme negligence. The other three officers, Ibrahim El-Morsi, Islam Abdel-Fattah and Mohamed Abdel-Aziz, were given suspended sentences. In June, those sentences were overturned by a lower appeals court. The coming retrial will be the final trial for the officers, as Egyptian law only permits two appeals.

An Argentine federal prosecutor on Jan. 14 accused the country's president, Cristina Fernández de Kirchner, of complicity in covering up Iran's involvement in a 1994 terrorist attack. The bombing of the Argentinine Jewish Mutual Association is said to have been one of the country's worst attacks, resulting in 85 deaths. The prosecutor, Alberto Nisman, requested that Judge Ariel Lijo interrogate the president and the foreign minister for "being authors and accomplices of an aggravated cover-up and obstruction of justice regarding the Iranians accused of the Amia terrorist attack," and seizing 200 million pesos worth of assets. The prosecutor cited phone tap recordings that show how the current administration negotiated with the Iranian government to cover up Iranian officials involvement in return for the establishment of a trade of grain for oil that would ameliorate Argentina's energy deficit.

Amnesty International called Jan. 15 for the release of three anti-slavery activists who were imprisoned in Mauritania. One of the imprisoned activists is prominent opposition politician Biram Ould Dah Ould Abeid, who was the runner-up in last June's presidential elections. The former presidential candidate is also the president of the Initiative for the Resurgence of the Abolitionist Movement (IRA) and won a UN Human Rights Prize in 2013. The three activists were given two-year sentences after being convicted of membership of an unrecognized organization and of taking part in an unauthorized assembly. The court acquitted seven other activists. Protesters outside the courthouse demonstrating against the judgment were dispersed by police with batons and tear gas. The IRA members that were arrested were engaged in a peaceful campaign to raise awareness about land rights for people of slave descent. Slave descendants who work on the land do not have any rights and must give a portion of their crops to their traditional masters. Police broke up the peaceful IRA meeting due to the absence of documents authorizing the group to meet, despite the fact that the IRA had requested the documents. AI called the sentence "politically motivated."

A group of US senators on Jan. 13 proposed legislation (PDF) that would place a moratorium on the release or transfer of prisoners from Guantánamo Bay. Republican Senators Kelly Ayotte (NH), John McCain (AZ), Lindsey Graham (SC) and Richard Burr (NC) touted  the new bill as the best course of action to protect US national security. The act, titled "The Detaining Terrorists to Protect America Act of 2015," would halt all releases of Guantánamo detainees with high or medium risk ratings, issue more prohibitions ontransfers and provide more transparency on how detainees' risk levels are determined. Ayotte stated, "It's clear that we need a 'time out' so that we do not re-confront the terrorists that we had captured and are currently in Guantánamo." The new legislation will place pressure on the White House as the Obama administration released 28 prisoners from Guantánamo in 2014.

The retrial of former Guatemalan dictator Efrain Rios Montt on charges of genocide and crimes against humanity was delayed on Jan. 5. Two of the three judges on the panel accepted the defense's motion that the third judge, Judge Jeannette Valdez, should recuse herself from the trial on the grounds that she is biased because she wrote her master's thesis on genocide. Rios Montt is being tried for ordering military operations that led to the torture, rape and murder of 1,771 indigenous Ixil Mayan between 1982 and 1983, part of Guatemala's bloody 1960-1996 civil war. Rios Montt was convicted on these charges in 2013 and sentenced to 80 years in prison, but 10 days later his sentence was overturned by the Constitutional Court on procedural grounds and a retrial was ordered.
