Kidnappers in Nigeria have killed at least 35 people they abducted from a village in the country’s northwestern Zamfara state despite ransoms being paid for their release, officials said Tuesday.

Details have emerged about a massacre of at least 32 people, including women, children, and a three-month-old baby, in what Christians called “a brutal attack” on the mainly Christian village of Jebu, in Nigeria’s northern Plateau State.

Residents in Nigeria’s Plateau State are reeling from attacks by Islamist hardliners that killed dozens of civilians, most of them predominantly Christian farmers, several sources said.
