Eight people were killed on Tuesday when a suicide bomber blew himself up outside a livestock market in northeast Nigeria, a local lawmaker and a resident told AFP.

The blast happened at about 1:15 pm (1215 GMT) in the village of Garkida in Adamawa state, said state assembly lawmaker Jerry Kundusi and witness Abdullah Musa.

"We don't know the identity of the assailant but it's obvious it's the work of Boko Haram insurgents," said Kundusi.
