Nigeria mourns 32 killed as military plane crashes into swamp

Nigeria's President Bola Tinubu has declared three days of national mourning after a military aircraft crashed in southern Ondo State, killing 32 people.

In February of the same year, seven people died after a military plane crashed short of a runway in the capital Abuja.

The Nigerian Air Force plays a key role in the country's military operations, including efforts to tackle armed groups and insecurity in several parts of the country.
