Suicide bombers have attacked two different places in and around the city of Maiduguri, north-east Nigeria, killing at least 13 people and wounding eight others.

The University of Maiduguri was targeted and a female member of staff lost her life.

In the second attack, four female suicide bombers blew themselves up in two villages just outside Maiduguri, killing 12 more people.

Maiduguri, capital of Borno state, is one of the cities worst hit by an insurgency led by Islamist militant group Boko Haram
