But a second bomber was shot dead by troops deployed in the town before she could detonate her explosives, the source said.
“A suicide bomber blew herself up this morning in Amchide” on the Nigerian border, a regional security source said, speaking on condition of anonymity and giving a toll of 29 wounded.
The attack occurred on market day when the town was filling up with early-morning shoppers, a local civil defence group official said.
“There were many people hurt, I saw about 20,” he said.
“After the attack, the market emptied.”
