Bombs exploded at three locations in Maiduguri, the capital of Nigeria's northeastern Borno State, leaving an undetermined number of people dead and injured, according to emergency officials cited by The Associated Press. The blasts occurred on Monday night at the entrance to the University of Maiduguri Teaching Hospital and at two markets known locally as Post Office and Monday Market.

Sirajo Abdullahi, the National Emergency Management Agency's head of operations in Maiduguri, said casualties were still being treated at the hospital and that officials could not provide a confirmed figure before completing a count. Authorities described the incidents as possible suicide bombings, but no group had claimed responsibility at the time of the report.

Accounts from people involved in the emergency response illustrated the pressure on medical services while also showing why an official toll remained unsettled. Bagoni Alkali, who said he transported wounded people to the hospital, estimated that more than 200 injured patients were receiving care and said many people had died at the scene. Mohammed Hassan, a member of a volunteer group that assists security forces, said he had evacuated 10 bodies from the Post Office and Monday Market areas. He also reported that some victims died after reaching the hospital and appealed for blood donations. Those witness estimates had not yet been reconciled with an official casualty count.

The blasts followed separate security activity earlier that day. Nigeria's military said it had repelled attacks by suspected Islamist militants on Maiduguri's outskirts during the early hours of Monday. The AP report did not establish a connection between that fighting and the later explosions. It also did not report arrests, identify suspects or describe evidence assigning the blasts to a particular organization.

Borno Governor Babagana Umara Zulum condemned the bombings and expressed sympathy for victims and their families. He urged residents to remain calm, continue their normal activities and alert security agencies to suspicious movement.

Maiduguri has long been central to Nigeria's campaign against Boko Haram and related armed factions. The broader insurgency has persisted for more than a decade, although attacks inside the state capital had become less frequent in recent years following military operations. Armed groups had recently intensified attacks on military bases elsewhere in northeastern Nigeria, according to the AP account.

The immediate priorities after the March 16 explosions were treating the injured, accounting for casualties across the three sites and determining who carried out the attacks. Until emergency agencies completed that work, witness figures offered an indication of the scale but not a definitive total.
