Kano, Nigeria (CNN) -- An explosion near a bank killed at least 10 people in northeastern Nigeria on Friday, witnesses and rescue volunteers said.
People were lined up at an ATM outside a bank on the outskirts of the town of Azare when the explosion happened, witnesses said.
The witnesses said the blast appeared to have come from a plastic bag near the bank.
Police comments about what caused the explosion weren't immediately available. Azare has been the site of previous attacks by the Islamist militant group Boko Haram.
