A child suicide bomber detonated an improvised explosive device at a mosque in Nigeria's northeastern state of Borno early Tuesday, killing one other person, a national emergency response team said, China's Xinhua news agency reported.

In a short electronic message to Xinhua, the northeast office of Nigeria's National Emergency Management Agency (NEMA) said the incident occurred at a mosque in Dalori town located on the outskirts of Maiduguri, the Borno State capital.

The suicide bomber was aged between eight and 10 years old, said Abdulkadir Ibrahim, a spokesman of NEMA in the region.

According to him, the body of the bomber was so mangled and shredded that only health personnel or experts could determine whether it was that of a boy or a girl.

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 suicide attack.

The terror group claimed responsibility for two suicide attacks on a mosque inside the staff quarters of the University of Maiduguri in Borno State on Jan. 16.

At least five people were killed and 15 injured in that particular attack carried out by a seven-year-old boy and an adult, according to local police.

Dalori Quarters, where Tuesday's attack occurred, is close to the University of Maiduguri.

Boko Haram is suspected to be regrouping in Maiduguri after the Nigerian military dislodged them from the Sambisa Forest, their last enclave in the West African country, last month.
