The attacks come more than a month after the group abducted an estimated 276 girls from a boarding school in Chibok, also in northeastern Nigeria. Dozens escaped, but more than 200 girls still are missing.
Boko Haram translates as "Western education is a sin" in the Hausa language. The militant group says its aim is to impose a stricter enforcement of Sharia law across Nigeria, Africa's most populous nation, which is split between a majority Muslim north and a mostly Christian south.
