Witnesses say an explosion at a rural market in northeast Nigerian has killed nine people and wounded at least 14. They blamed Boko Haram extremists.

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 kilometres 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.

On Friday, Boko Haram recaptured the border town of Marte.

On Saturday, the military said it destroyed 10 insurgent forest camps.
