Advocacy group Human Rights Watch (HRW) said May 1 that it has found new evidence that the Syrian government has used chemical weapons in at least four recent attacks targeting civilians. The report, "Death by Chemicals: The Syrian Government's Widespread and Systematic Use of Chemical Weapons," states that local residents and activists in Khan Sheikhoun town identified at least 92 people who likely died from chemical exposure. It also named three pieces of additional evidence to support the finding that the government has been committing crimes against humanity:

Thousands of indigenous protesters clashed with police outside the congress building in Brasilia during an April 26 demonstration over territorial and land rights in the Brazilian Amazon. Police fired rubber bullets and tear-gas when some protesters tried to reach a ramp leading into the National Congress. Indigenous demonstrators in face-paint and traditional head-dresses shot arrows at police in return. The demonstration was called to oppose measures being pushed by the powerful agribusiness bloc in Brazil's Congress, the Bancada Ruralista, that would threaten indigenous lands in the Amazon. Topping the list is Proposed Constitutional Amendment 215, or PEC 215, that would shift responsibility on demarcating indigenous lands from the executive to Congress, where the powerful farm lobby holds sway.

Speaking before the World Jewish Congress in New York April 23, UN Secretary-General Antonio Guterres stated: "A modern form of anti-Semitism is the denial of the right of the State of Israel to exist. As secretary-general of the United Nations, I can say that the State of Israel needs to be treated as any other state, with exactly the same rules." He said this "does not mean I will always be in agreement with all the decisions made by any government position taken by any government that sits in Israel," but that he supports "the absolutely undeniable right of Israel to exist and to live in peace and security with its neighbors."

"More Than 7,000 People Evacuated From 4 Besieged Syrian Towns." That's the somewhat misleading headline in the New York Times of April 14. Reads the lede: "After nearly two years of punishing siege and bombardment by their enemies, more than 7,000 people were bused out of four towns in Syria on Friday in the most recent population transfer during six years of war." Note the euphemistic language. This isn't "evacuation," which implies it is voluntary and in response to some objective disaster. This is "sectarian cleansing," part of an intentional Assad regime strategy to purge its growing areas of control of Sunnis, all of whom are apparently deemed official enemies. "Population transfer," as it is dubbed in the lede, is another euphemistic term, one all too familiar to those who have followed the growing consensus for territorial purging of perceived ethno-sectarian enemies in Israel.

Hearings began in Spain on April 10 regarding potential war crimes committed by President Bashar Assad's regime in Syria. The case is a result of a Spanish national's brother being abducted and tortured in Damascus before being executed in 2013. The family claims that the brother was not part of an opposition group and just a truck driver making a delivery. The family was able to identify the body after a forensic photographer smuggled the photos out of Syria. The photographer may testify in the case next month. The investigation involved nine of Assad's closest aides but not Assad himself due to his immunity. Spain is the first to hold a criminal investigation of potential war crimes into Syria, as Russia has blocked referral of the Assad regime to the International Criminal Court.

An apparent chemical attack on the rebel-held town of Khan Shaykhun, Idlib governorate, left at least 80 dead April 4. After a bombing of the town, medics reported a "bloodless massacre," saying that they were treating people with symptoms including fainting, vomiting and foaming at the mouth. The hospital where gas-attack victims were being treated was itself bombed in the immediate aftermath, "bringing down rubble on top of medics as they worked," according to AFP. The opposition-run Health Department in Idlib has provided a list of the names of some 70 dead, with more still being identified. Some of the victims were brought across the border to Turkey for treatment, where several died. Turkish authorities say autopsies revealed evidence of exposure to sarin. The UN Security Council immediately called emergency talks on the attack. On April 4, US warships in the Mediterranean launched 59 Tomahawk cruise missiles at Shayrat air-base outside Homs, from where the Khan Shaykhun attack is said to have been launched. This constituted the first US attack on an Assad regime target throughout the course of the war (not counting last year's accident, immediately apologized for).

Spain's top court on March 27 agreed to investigate claims by a Spanish woman who alleges her brother was tortured and murdered by Bashar al-Assad's security forces. According to the woman, who is identified only as AH for security reasons, her brother was executed in 2013 at a detention facility in Damascus. Spanish High Court Judge Eloy Velasco has asked Syrian authorities to appoint legal representation in Spain for the nine security officers implicated in the torture and murder of the litigtant's brother. The case is the first criminal complaint accepted against President al-Assad's security forces by a European court. The lawyers for AH contend that Spanish courts have jurisdiction over the complaint due to the woman's status as a Spanish citizen. Velasco determined that the complaint has standing in Spain's courts under international norms that consider family members of those who have "disappeared" as a result of international crimes to be equally considered victims of those crimes.

Seven army officers have been arrested and charged with war crimes in the Democratic Republic of Congo (DRC), according to government officials at a press conference on March 18. The charges stem from a massacre of unarmed civilians in Kasaï-Central Province in February that was recorded and widely shared on social media. Congolese military auditor general Joseph Ponde Isambwa said that all seven arrested soldiers were members of the Armed Forces of the Democratic Republic of Congo, or FARDC. Ponde said the charges against the officers include "war crime by murder, war crime by mutilation, war crimes by cruel inhuman and degrading treatment and denial of an offense committed by persons subject to military jurisdiction."
