Two female suicide bombers struck a crowded market in north-east Nigeria on Sunday, killing at least four people and injuring dozens.
An eyewitness in the city of Potiskum, in Yobe state, told the BBC that the second bomb went off shortly after the first, hitting those helping victims. On Saturday, a bomb strapped to a girl aged around 10 killed at least 19 people in Maiduguri, in Borno state.
The attacks come amid an offensive by Boko Haram militants in the region.
A doctor at the scene in Potiskum said he saw the remains of suicide belts on the two women, who looked to be in their early 20s. A security official also said that it appeared the bombs had been remote-controlled.
“The second bomber was terrified by the explosion and she tried to dash across the road but she also exploded,” he said.
No group claimed responsibility, but reports suggest the blasts could have been carried out by Boko Haram, who has used female suicide bombers in the past.
The violence in north-east Nigeria has been relentless in recent weeks. Last week, people fleeing the town of Baga said several hundred people were killed there by Boko Haram gunmen in recent days.
