At least 65 Nigerian soldiers have been killed in attacks by jihadist militants across the country's northeast over the past two weeks, according to reports.

On March 5 and 6, gunmen from Islamic State West Africa Province (ISWAP) overran four military bases in Borno state, the center of Nigeria's ongoing insurgency. Nigerian newspaper The Punch reported that approximately 40 soldiers were killed in these specific attacks.

The militant group also reportedly abducted 300 civilians during the raids, adding to the humanitarian crisis in the region. ISWAP is an offshoot of Boko Haram that pledged allegiance to the Islamic State.

Borno state has been the epicenter of a jihadist insurgency that has plagued northeastern Nigeria for over a decade. The conflict has displaced millions of people and created one of the world's largest humanitarian crises.

The recent attacks highlight the ongoing security challenges facing Nigerian forces as they attempt to contain what has been described as one of the world's deadliest terror groups. The Nigerian military has been conducting operations against various jihadist factions in the region for years.
