The wives of Nigerian soldiers have protested against their husbands being sent to fight militant Islamist group Boko Haram, a demonstrator has said.
The protest at the main military barracks in north-eastern Maiduguri city came as the government vowed to retake Gwoza town from the militants.
Hundreds of people were killed when Boko Haram seized Gwoza last week, the area’s senator, Ali Ndume, said.
Boko Haram is fighting to create an Islamic state in Nigeria.
It is the latest sign of growing dissatisfaction with the military top brass, he says.
Soldiers have repeatedly complained Boko Haram has superior firepower and they are in position to confront the militants.
In May, some soldiers opened fire on their commander, Maj-Gen Ahmed Mohammed, at Maiduguri’s Maimalari barracks, blaming him for the killing of their colleagues by Boko Haram fighters.
The violence in Nigeria has forced some 250,000 people from their homes this year, according to the government’s relief agency.
More than three million people are facing a humanitarian crisis.
A state of emergency was declared in Borno and two other north-eastern sates last year to help the military crush the insurgency but the militants have stepped up attacks since then.
In April, Boko Haram caused global outrage by abducting more than 200 schoolchildren in Chibok town in Borno state.
The group has also carried out a wave of bombings and assassinations, including that of moderate Muslim leaders opposed to its ideology.
