The Organisation for the Prohibition of Chemical Weapons (OPCW) announced April 29 that it would begin a fact-finding mission into allegations of the use of chlorine gas in Syria. Although both rebel forces and the Syrian government acknowledge that the chemical weapon was used on the Syrian town of Kafr Zita, both factions deny responsibility for the attack. Chlorine was not a chemical Syria was required to give up, but the use of chlorine gas is prohibited under the Chemical Weapons Convention, to which Syria is a signatory. Some western governments believe that Syria has failed to declare all the chemical weapons in its possession, including chlorine gas, and has retained some of its chemical stockpile.

Russia's upper house of parliament on April 29 approved a set of bills that apply new restrictions on the Internet and blogging, a move widely criticized by both pro-democracy activists and Russia's technology sector alike. Critics of the draft laws affecting the Internet, which are expected to be signed by President Vladimir Putin soon and enforced in August, have expressed fear that the legislation is an attempt by Putin to silence opponents on the Internet. The bill causing the most concern leaves bloggers subject to greater regulation and legal liability, equating them to media outlets. This bill, which would require bloggers with 3,000 or more page visits per day to reveal their identities and abide by many of the same requirements as the mass media, is one of three bills in the package that impose control over the dissemination of information on the Internet and online payments and inflicts harsher punishment for terrorism and extremism. The legislation also requires that social networking sites and blog hosts store data on site users for at least six months in case the authorities need access for investigations. Supporters of the bill, including the United Russia party, have stated that the restrictions are needed to fight online extremism.

An Egyptian judge on April 28 sentenced 683 alleged supporters of the banned Muslim Brotherhood to death, including the group's supreme guide, Mohamed Badie. The judge also confirmed the death sentence of 37 of 529 Muslim Brotherhood supporters sentenced to death in March. The remaining defendants sentences were commuted to life prison. Under Egyptian law the death sentence recommendations in the case of Badie and the 682 other alleged supporters will be passed to the Grand Mufti of Al Azhar, the country's leading religious official, who will provide his non-binding opinion to the presiding judge. The defendants were all accused of taking part in violence in the southern governate of Minya on Aug. 14. The guilty verdict and death sentences are still subject to appeal.

The Libyan News Agency reported on April 27 that the son of Moammar Qaddafi, Saif al-Islam Qaddafi, and other ex-officials have appeared for their trial via video conferencing. Saif al-Islam Qaddafi appeared at his trial through video-conferencing because he has been held in Zintan by a militia since 2011. Human Rights Watch reported in February that Libya has failed to grant due process rights to Qaddafi and other detained officials. There are 37 defendants in the trial, facing a variety of charges including the killing of protesters during the 2011 civil war. The trial commenced earlier in April.

The Periodic Review Secretariat, a national security panel under the authority of the US Department of Defense (DoD), on April 24  recommended (PDF) the release of a Yemeni prisoner currently held at Guantánamo Bay. The prisoner, Ali Ahmad Mohamed al-Razihi, was suspected of acting as a bodyguard for Osama bin Laden and has been held at Guantánamo since 2002. The Periodic Review Secretariat determines whether certain individuals detained at Guantánamo represent a continuing significant threat to the security of the US such that their continued detention is warranted. In making the determination, the security review panel considered the detainee's plans for the future and the level of his involvement with al-Qaeda, including his behavior throughout detention. The journalist and Guantánamo expert Andy Worthington released a copy of al-Razihi's statement  delivered before the review board of the Periodic Review Secretariat on March 20.

Lawmakers in Kosovo on April 22 voted 89-22 to create an EU-backed court that will investigate crimes committed by ethnic Albanian rebels during the 1998 war with Serbia. The move follows international pressure for Kosovo to open a state investigation into civilian killings committed by the rebel side. The court will be based in Kosovo, though most of the work will be carried out in the Netherlands. Similar to the operations of the International Criminal Tribunal for the former Yugoslavia (ICTY), the court will be run by international judges and lawyers. Rebels during the conflict allegedly killed approximately 400 civilians.

A Saudi Arabian court on April 21 sentenced three people to death for their roles in attacks on expatriate resident compounds in Riyadh in May 2003, bringing the total death sentences to eight. Another 77 people have been sentenced to prison terms ranging from two to 35 years by the court, which was created to handle terrorism cases. The 2003 attacks, in which blasts at three residential compounds in Riyadh left 35 people dead, were part of a three-year campaign by al-Qaeda aimed at destabilizing Saudi Arabia. The identities of the 85 defendants have not been disclosed, though the Sabq news website has reported that five men sentenced to death a day earlier had been found guilty of assembling the car bombs used to attack the compounds. They have 30 days to appeal their sentences, all of which were handed down for charges of taking part or abetting in the attacks.

The UN Mission in South Sudan (UNMISS) on April 21 alleged that armed rebels engaged in ethnically targeted killings during a raid on the northern city of Bentiu last week, resulting in more than 200 civilian deaths and 400 injuries. Rebels loyal to deposed vice president Riek Marchar reportedly sought to capture Bentiu, the capital of Unity state, in order to seize the city's significant oil fields and installations. The UN reported that the massacres took place at a mosque, a hospital and an abandoned UN compound.
