MAIDUGURI, Nigeria (AP) — Officials say suspected Islamic extremists shot and killed four people involved in education programs in northeast Nigeria, including a man in charge of a program to feed poor students.

The killings happened Monday on the outskirts of Bama in Borno state, a region long under attack by a radical Islamic extremist network known as Boko Haram. Authorities say the four were killed as they tried to flee the gunmen.
