The International Tribunal for the Law of the Sea ruled (PDF) Sept. 23 in favor of Ghana in a lengthy maritime dispute with Ivory Coast. The case, which was brought to the international body by Ghana in 2014, was an attempt to clarify the boundary between the two countries, as both countries were vying for oil in the contested area. The court unanimously ruled in favor of Ghana, dismissing the claim that Ghana violated the territorial rights of Ivory Coast when it expanded its oil exploration in the area. The ruling definitively creates a boundary, in the form of a straight line running from the land boarder of the two nations. The ruling came in accordance with the UN Convention on the Law of the Sea.

At least four were killed when Nigerian army troops raided the home of Nnamdi Kanu, leader of the Indigenous People of Biafra (IPOB), in Umuahia, Abia state, Sept. 14. Unconfirmed reports put the number of dead in the raid as high as 22, and it is unclear if Kanu himself was captured, killed or escaped. The raid comes two days after what local media called a "communal clash" between IPOB militants and ethnic Hausa residents in Oyigbo, Rivers state, leaving an undetermined number of casualties. A media representative of President Muhammadu Buhari's office issued a statement claiming a "deliberate and sinister agenda by IPOB to provoke soldiers into killing innocent people," charging the group with "accusing the government of ethnic cleansing against Igbos...for the sole purpose of gaining sympathy."

Ntabo Ntaberi Sheka, the leader of a militia in the Democratic Republic of Congo (DRC), turned himself in to UN Organization Stabilization Mission in the DR Congo (MONUSCO) on July 26. The DRC took out a warrant for Sheka's arrest in 2011 after his forces allegedly raped at least 387 civilians during a four-day period in 2010. The militia is also accused of murdering 70 civilians between 2010 and 2015. The UN sanctioned Sheka in 2011 for war crimes, including mass rapes and crimes against children. MONUSCO said that Sheka surrendered near the town of Walikale, North Kivu province, and will be transferred to DRC authorities to eventually stand trial.

Amnesty International in a report issued July 20 accused Cameroon of torturing suspected supporters of Boko Haram in its military campaign against the jihadist group. According to the human rights organization, hundreds of suspects have been "subjected to severe beatings, agonizing stress positions and drownings, with some tortured to death" at the hands of government authorities. Amnesty documented 101 cases of secret detention and torture within the last four years. Alioune Tine, Amnesty's regional director for West and Central Africa, said, "These horrific violations amount to war crimes." Amnesty also observed American and French military personnel at one of the bases while the detention and torture was taking place. The organization is calling for the US and France to investigate the extent of knowledge that their military personnel may have of war crimes in Cameroon.

The International Criminal Court (ICC) ruled (PDF) July 6 that South Africa violated its treaty obligations by failing to arrest Sudanese President Omar al-Bashir when he visited the country in 2015. Two arrest warrants (PDF, PDF) have been issued for al-Bashir involving numerous charges including "crimes against humanity, war crimes, and crimes of genocide." South Africa contended that because al-Bashir has immunity from criminal proceedings under customary international law that had not been waived in Sudan, the court was precluded from compelling South Africa to detain and surrender him.

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.

Armed groups continue to commit war crimes in the Central African Republic (CAR), according to a report released July 5 by Human Rights Watch (HRW) detailing violence in three central provinces between November 2014 and April 2017. During that time period, HRW documented at least 566 civilian deaths at the hands of the Seleka and Anti-Balaka groups. Armed groups also destroyed no fewer than 4,207 homes, forcing people to flee and causing the deaths of 144 children and elderly people. Those responsible for the deaths have not been "detained, arrested or otherwise held accountable," and are still free to roam the areas where their crimes occurred. In addition to seeking international support for improved civilian protection, the report also asks the UN and other individual governments to back the Special Criminal Court (SCC) financially and politically. Although President Faustin-Archange Touadéra has praised the SCC, the government has "lagged in steps to operationalize" it. The SCC, an institution within the CAR's justice system with international judges and prosecutors, has the "unique chance to hold accountable the perpetrators of these grave crimes."

A UN human rights expert warned June 20 that the Central African Republic (CAR) "must act now" to protect its population and implement justice. According to Marie-Thérèse Keita Bocoum, the expert on human rights for the CAR, armed groups are spreading throughout the country at a worrying rate, and a lack of response from the government to defend civilians has led to revenge attacks, public outrage, and "cries of distress" from citizens. The announcement from the UN comes on the heels of a peace accord signed by the CAR and most of the armed groups, aimed at ending the ethnic and religious conflict that has killed thousands. The peace accord was mediated by the Roman Catholic Sant'Egidio peace group (which brokered the end of the civil war in Mozambique in 1992) and was signed in Rome.
