No group has claimed responsibility for the attack, but police suspect the Eastern Security Network, the paramilitary wing of the proscribed separatist group Indigenous People of Biafra.The secessionist campaign in southeastern Nigeria dates back to when the short-lived Republic of Biafra fought and lost a civil war from 1967 to 1970 to become independent from the West African country. An estimated 1 million people died in the conflict, many from starvation.

The rights group said “international law requires the Nigerian government to promptly investigate unlawful killings with a view to bringing perpetrators to justice.”One suspect connected to the attack was killed in a joint operation by law enforcement agencies, police spokesperson Okoye Henry said in a statement.“An intensive manhunt is ongoing to apprehend the fleeing suspects and bring them to justice,” Henry said.

Two of the group’s prominent leaders, Nnamdi Kanu and Simon Ekpa, are in custody in Nigeria and Finland, respectively.Kanu is standing trial on a seven-count charge bordering on terrorism and treasonable felony. He has pleaded not guilty to the charges.

The Nigerian government said Friday it has not begun extradition proceedings but is in talks with Finnish authorities to ensure Ekpa is held accountable for his alleged actions.

For many years Nigeria — Africa’s most populous nation with at least 210 million people — has been wracked by violence related to the activities of armed extremist groups.In April, Health Secretary Robert F. Kennedy Jr. and FDA Commissioner Marty Makary announced that they would take steps to eliminate synthetic food dyes in the U.S. food supply by the end of 2026, largely through voluntary efforts from the food industry. The officials also said they would revoke authorization for two little-used artificial dyes, Citrus Red No. 2 and Orange B, and accelerate the timeline to remove Red 3, a food color

because of a link to cancer in laboratory rats.The FDA plans to initiate the process to revoke those colors “within the coming months,” a spokesperson for the Department of Health and Human Services said.
