text:  Paul Njia in Eastern Chad. Now, an update on a story you may have heard on the programme yesterday, the attack by suicide bombers in north-eastern Nigeria on Saturday. At least 18 people died and more than 40 were injured in the three attacks in the regional town of Goza in Borno State. The attackers, all thought to be female, targeted a wedding, a hospital and a funeral.
