Merchant Abubakar Garba says today's bomb appeared to have been planted between the sheep market and vegetable stalls at Garkida. Others say it was a suicide bomber.
Garkida is 165 kilometers north of the Adamawa state capital, Yola. State legislator Jerry Kundisi confirmed the blast killed nine people and injured 14.
It's the latest in a slew of attacks that have occurred since multinational forces broke up Boko Haram's so-called Islamic caliphate by driving the insurgents out of all northeastern towns.
