At least 16 people, including 11 soldiers, have been killed in terrorist attacks in Nigeria’s northeastern Borno state, military and militia sources said Saturday.

Rival factions of Boko Haram launched the attacks on military and civilian targets between Thursday and Saturday, they said.

On Thursday, fighters from the ISSIS-aligned Islamic State West Africa Province ambushed a military convoy near Mauro village in Benisheikh district, a military source told AFP.
