"Seven dead bodies have been evacuated from the scene of the blasts," said a Red Cross official.
Maiduguri is the birthplace of the insurgency by militant Islamist group Boko Haram, which has killed thousands and displaced 2.1 million people since 2009 in its attempt to create a state adhering to strict sharia law in the northeast.
The explosions are the worst attacks on the city, capital of Borno state, since 54 people were killed and 90 injured in bombings three weeks ago.
