The US Supreme Court on June 26 ruled 5-to-4 (PDF) in Trump v. Hawaii that President Donald Trump's proclamation restricting entry from particular Muslim-majority countries was "squarely within the scope of presidential authority" under the Immigration and Nationality Act. The court also found that plaintiffs challenging the proclamation were unlikely to succeed on their claim that the ban violates the Establishment Clause of the First Amendment. Chief Justice John Roberts wrote for the majority: "[T]he Government has set forth a sufficient national security justification to survive rational basis review. We express no view on the soundness of the policy. We simply hold today that plaintiffs have not demonstrated a likelihood of success on the merits of their constitutional claim." The ruling overturns a preliminary injunction issued by the Ninth Circuit Court of Appeals in December, which blocked the policy from taking effect. The Supreme Court remanded the case back to the lower courts for "further proceedings."

Thousands of women and girls who survived the brutal rule of the Boko Haram armed group have since been further abused by the Nigerian security forces who claim to be rescuing them, said Amnesty International in a new report released May 24. Entitled They Betrayed Us, the report reveals how the Nigerian military and its paramilitary arm, the Civilian Joint Task Force (CJTF), have separated women from their husbands and confined them in remote "satellite camps," where they have been raped, sometimes forced to submit in exchange for food. Amnesty International has collected evidence that thousands of people have starved to death in the camps in Borno state since 2015.

Niger's army on July 6 killed at least 14 displaced persons who were apparently mistaken for jihadists in the restive southeast, where Boko Haram militants have staged regular attacks. Soldiers were patrolling a militarily restricted zone around the village of Abadam near Lake Chad when they opened fire on what turned out to be unarmed peasants. Yahaya Godi, official in charge of the Diffa region, said: "Any individual seen in the area is considered Boko Haram." Thousands of people have been displaced from the southeastern Diffa region, and civilians have been banned from many areas in response to raids by Boko Haram from across the border in Nigeria. Many, however, have been returning to their lands to tend their crops, fearing hunger and permanent displacement.

The US Supreme Court on June 26 agreed to review (PDF) the Trump administration's travel ban, partially lifting the temporary injunction that had blocked the ban's enforcement. The administration sought review of decisions issued by the US Courts of Appeal for the Fourth and Ninth circuits last month. The Supreme Court's order permits execution of the travel ban, but it "may not be enforced against an individual seeking admission as a refugee who can credibly claim a bona fide relationship with a person or entity in the United States."

A court in Senegal convicted former Chadian dictator Hissène Habré of crimes against humanity committed during his rule from 1982 to 1990, and sentenced him to life imprisonment on May 30. He was found guilty of sex slavery, rape and the ordered killings of an estimated 40,000 people. The trial marks the first time a court with backing from the African Union has tried a former ruler for human rights violations, and also the first time a former African head of state was found guilty by an another African country. Habré has 15 days to appeal the sentence. Human Rights Watch lawyer Reed Brody, who initiated the trial, stated: "This verdict sends a powerful message that the days when tyrants could brutalize their people, pillage their treasury and escape abroad to a life of luxury are coming to an end. Today will be carved into history as the day that a band of unrelenting survivors brought their dictator to justice."

President Barack Obama formally notified Congress Oct. 14 that 90 US troops have been mobilized to Cameroon—the first contingent of a 300-strong force to assist in the struggle against Boko Haram. The force will conduct airborne intelligence, surveillance, and reconnaissance, but will not participate in ground combat operations (except in self-defense). Unarmed surveillance drones will also be deployed. The Pentagon said the move came at the invitation of Cameroon's government, which has been headed by strongman Paul Biya since 1982. Cameroon is part in a joint regional task force to fight Boko Haram along with Chad, Niger and Benin.

At least five suicide bombers on Oct. 10 targeted a village in Chad that is home to thousands of Nigerians who have fled Boko Haram violence, killing at least 36 people and wounding about 50 others in co-ordinated attacks. Authorities blamed Boko Haram for staging the attacks in the village of Baga Sola, near the Nigerian border. Nearly half of the dead resulted when two female suicide bombers hit the village market when it was at its busiest. The following day, two female suicide bombers carried out the attacks in the Cameroon village of Kangaleri, again targeting a market district and killing nine. Both western Chad and northern Cameroon hosts thousands of Nigerian refugees. Another 1.5 million are internally displaced within Nigeria. (AFP, CBC, Sahara Reporters, Anadolu Agency)

The Extraordinary African Chambers on Sept. 3 confirmed that war crime accusations have been filed against Chad's President Idriss Deby. The special tribunal in Senegal is overseeing the case against the former president of Chad, Hissène Habré (BBC profile), who was accused of crimes against humanity, war crimes and torture. A Senegalese lawyer, Mbaye Jacques Ndiaye, filed the charges against Deby to hold him responsible for the role he played in perpetuating the alleged crimes of his predecessor while he served as Habré's army chief.
