Abuja, Jan 16 : At least five persons were killed and over 15 injured when two suicide bombers attacked a university in Nigeria's Borno state on Monday, police said.
A seven-year-old boy detonated his improvised explosive device at a mosque inside the University of Maiduguri, Xinhua news agency quoted police chief Damian Chukwu as saying.
An official from the state Emergency Management Agency said a professor was among those killed.
Terror group Boko Haram, which has killed more than 20,000 and displaced 2.3 million people since the current insurgency started in 2009, is believed to be responsible for the attack.
Nigeria has made considerable gain on the Boko Haram front, with its security forces operating in the restive region dislodging the group's fighters from the Sambisa Forest, their last enclave in the country.
