Bauchi — Two girls blew themselves up on Monday near a crowded mosque in Maiduguri, killing about 30 people, witnesses said.
Fishmonger Idi Idrisa said one teenager exploded as she approached the mosque crowded with people from the nearby Baga Road fish market, performing afternoon prayers during the holy month of Ramadan.
The second teen appeared to run away and blew up further away, killing only herself, he said.
Civilian defense fighter Sama Ila Abu said he counted at least 30 corpses as he helped collect the dead.

A military bomb disposal expert has told the AP that most bombs carried by girls and women have remote detonation devices, meaning the carrier cannot control the explosion.
