Two female suicide bombers have killed 13 people in a market in northern Nigeria's main city, Kano, police say.
Residents say one of the bombs went off inside the market, and the other outside a place called Farm Centre which sells mobile phone accessories.
No-one has said they are responsible but militant Islamist group Boko Haram has previously targeted Kano. On Tuesday, more than 30 people were killed by a suicide bomber in Yola city in an attack blamed on Boko Haram.
In July Kano was attacked by a female suicide bomber who blew herself up outside a mosque killing herself and injuring another person. A more deadly attack in November 2014 killed more than 100 people at the central mosque.
Nigerian officials say many girls are forced to become suicide bombers, and are told that if they refuse they will be killed. The Global Terrorism Index says 6,644 deaths were attributed to Boko Haram in 2014, making it the world's deadliest militant group.
Witnesses told AFP news agency the explosions went off just after 15:00 GMT. Initials reports said five people had been killed. Police say the number has since risen to 13.
