• Armed gang members have killed at least 20 people in northwest Nigeria, targeting villages in Zamfara State.
• Security forces in Nigeria have rescued dozens of students and teachers who were kidnapped from schools in Oyo State, with eight suspects arrested and some killed.
• Kidnappings for ransom have become common in Nigeria, with attackers earning over $1.6 million in ransom payments in 2024, partly due to a security crisis fueled by the Boko Haram rebellion.

At least 20 people have been killed in northwest Nigeria after armed gang members attacked villages in Zamfara State, according to the AFP news agency.

"Today, between 3pm [14:00 GMT] and 4pm [15:00 GMT], a large number of bandits have invaded our communities, targeting all the people they meet," Nasiru Lauwali, the representative of the Sauna district in the local government zone of Talata Mafara, told AFP on Wednesday.

The attacks come amid increasing violence in northwest and central Nigeria, where armed gangs or bandits have raided villages in recent weeks. They are accused of stealing livestock and kidnapping residents for ransom.

Late on Tuesday, at least three suspected bandits were killed by security forces in the country's Kwara State, according to Nigeria's The Punch news website. The news service said that security forces managed to rescue a businessman, Tuhkur Sanni.

Kidnappings have become common in Nigeria, as armed groups seek large ransoms from the government and citizens.

The situation has been worsened by a security crisis, partly fuelled by the Boko Haram rebellion in the country's northeast. In 2024, attackers earned more than $1.6m in ransom payments, according to SBM Intelligence.

Dozens of students and teachers were rescued earlier this month, 56 days after they were kidnapped from three schools in the southwestern state of Oyo.

Eight of the suspected kidnappers were arrested and an unspecified number were killed, according to a statement issued by President Bola Tinubu.

Defence Minister Christopher Musa said the suspects planned to use the hostages as leverage to pressure the government to release some of their commanders from prison.
