12 killed in Nigeria bus bombing
Twelve people have died and 20 are injured following a suicide bomb attack in the north-eastern Nigerian town of Potiskum.
There was no immediate claim of responsibility for the blast but it bore the signs of similar attacks by Nigeria's home-grown Boko Haram Islamic extremist group.
Bus driver Adamu Isa said the man forced himself onto the bus and blew himself up. Hospital records show 12 people died and 20 were injured.
In the same town on Sunday a girl who looked about 10 carried explosives that detonated, killing herself and four others at a market.
Thousands of people have been killed in the five-year-old uprising to enforce strict Islamic law in Nigeria.
