Nigeria mourns 25 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.

Authorities say the plane was on a routine mission from Benin City to Lagos when it came down in a swamp near a naval base on Monday morning. After reaching the site, the aircraft was found to be submerged under water, officials said.

A resident told the BBC that clothes and shoes had been found at the site. Smoke could be seen rising from the area.

It is the deadliest crash involving a Nigerian military aircraft since 1992.

Tinubu offered his deepest condolences for the 25 passengers and seven crew members on board and has ordered a full investigation.

The president also ordered national flags to be flown at half-mast across the country as a mark of respect for those who died.

"This is a painful moment for our Armed Forces and for the entire nation," Tinubu said.

"Our Air Force personnel put their lives on the line every day to secure Nigeria. Their sacrifice will never be forgotten," he added.

Aviation Minister Festus Keyamo earlier said he had been informed "of the disappearance of a military aircraft with tail number NGR 931, enroute Lagos from Benin at 0913 hours earlier today".

He said "efforts to raise the aircraft on radio proved abortive" before subsequent confirmation that it had crashed near a naval base in Igbokoda, Ondo state.

He said search and rescue efforts were ongoing.

The crashed plane, described as an ATR-42 aircraft, carries between 30 and 50 passengers, according to its manufacturers.

The Nigerian Air Force has released the names of those killed, showing that most of those on board were military personnel.
