Fighting between Nigeria's military and Islamic extremists has killed at least 185 people in a fishing community in the nation's far northeast.
The fighting in Baga began on Friday and lasted for hours, sending people fleeing into the arid scrublands surrounding the community on Lake Chad.
The assault marks a significant escalation in the long-running insurgency Nigeria faces in its predominantly Muslim north, with Boko Haram extremists mounting a coordinated assault on soldiers using military-grade weaponry.
The killings also mark one of the deadliest incidents ever involving Boko Haram.
Authorities had found and buried at least 185 bodies as of yesterday afternoon, said Lawan Kole, a local government official in Baga.
Officials could not offer a breakdown of civilian casualties versus those of soldiers and extremist fighters.
Many of the bodies had been burned beyond recognition in fires that razed whole sections of the town, residents said.
Those killed were buried as soon as possible, following local Muslim tradition.
Brigadier General Austin Edokpaye, also on the visit, did not dispute the casualty figures.
Mr Edokpaye said Boko Haram extremists used heavy machine guns and rocket-propelled grenades in the assault, which began after soldiers surrounded a mosque they believed housed members of the radical Islamic extremist network Boko Haram.
Extremists earlier had killed a military officer, the general said.
Mr Edokpaye said extremists used civilians as human shields during the fighting.
"When we reinforced and returned to the scene the terrorists came out with heavy firepower, including (rocket-propelled grenades), which usually has a conflagration effect," the general said.
However, local residents who spoke to an Associated Press journalist who accompanied the state officials said soldiers purposefully set the fires during the attack.
Violence by security forces in the northeast targeting civilians has been widely documented by journalists and human rights activists.
A similar raid in Maiduguri, Borno state's capital, in October after extremists killed a military officer saw soldiers kill at least 30 civilians and set fires across a neighbourhood.
The Islamic insurgency in Nigeria grew out of a 2009 riot led by Boko Haram members in Maiduguri that ended in a military and police crackdown that killed some 700 people.
The group's leader died in police custody in an apparent execution.
From 2010 on, Islamic extremists have engaged in hit-and-run shootings and suicide bombings, attacks that have killed at least 1,548 people before Friday's attack, according to an AP count.
