At least 32 people were killed and 80 wounded after an explosive device went off at a market in the northeastern Nigerian city of Yola, humanitarian agencies say.
''Tirty-two people were killed and 80 have been injured,'' - Reuters quoted a Red Cross official as saying., Another official from the National Emergency Management Agency (NEMA), Alhaji Sa'ad Bello, later confirmed the same numbers of casualties.
It is still unclear who is responsible for the blast, but the armed group Boko Haram has carried out attacks on Yola in the past, including suicide bomber attacks and other bombings.
