Extremists attacked and abducted a number of worshipers in Nigeria's Niger State, authorities said on Saturday.

Police said the armed men attacked the villages, including Gidan-Zana and Kpenya, before storming the latter village's mosque during Friday prayers.

"Soon after finishing the normal Friday prayer, the armed group [...] in their hundreds, wielding guns, knives and machetes, began to attack us," one survivor told the AFP news agency. "They slaughtered some of our people, saying we are not practicing the true teachings of Islam."

Local residents told the AFP and Reuters news agencies that dozens of people — as many as 60 — were kidnapped.

Witnesses also told AFP that the armed men killed several people, although according to police, "the developing report indicated that no life ‌was ​lost."
