Two explosions at a market in Nigeria's north-eastern state of Yobe have killed at least 50 people and injured dozens of others.

The attack happened as people were doing last-minute shopping as the Muslim Holy month of Ramadan comes to an end.

One witness said many of the bodies were of children.

According to CNN, the bombers included a young girl and an elderly woman.

The Islamist militant group Boko Haram has stepped up attacks since May but has not yet commented on the attack.
