Atleast 70 people aboard a boat have died when it capsized in a flood-swollen river in Anambra state.

An estimated 85 people were said to have been on boat on Friday when flooding of the Niger River caused it to tip over.

“The boat reportedly carrying 85 persons capsized following rising floods in Ogbaru area of the state, with emergency services confirming a death toll of 76,” the office of Mr. President was quoted have said.

He directed the emergency services to provide relief to the victims.

“I pray for the repose of the souls of the deceased and for everyone’s safety, as well as the well-being of the family members of the victims of this tragic accident,” he added.

Earlier on Sunday, the emergency services said rising water level was hampering rescue efforts.

“The water level is very high and too risky for a smooth search and rescue operation,” Thickman Tanimu, the southeast coordinator of the National Emergency Management Agency (NEMA) told AFP.

He said the flooding was the worst the country has seen in years, with the water level around one-tenth higher than a decade ago.

NEMA requested the Nigerian Air Force provide helicopters for the rescue operation.

The Governor of Anambra state  Charles Soludo urged residents of flood-ravaged areas to relocate, while adding that the government would provide relief to those affected by the disaster.

“This development is still a shock to the government and good people of Anambra State. I sympathise with the families of people involved,” Soludo said in a statement.

Boat accidents occur regularly in Nigeria because of overloading, speeding, poor maintenance and disregarding navigation rules.

Since the start of the rainy season, many regions of the West African nation of more than 200 million people have been devastated by floods.

More than 300 people have been killed and at least 100,000 made homeless, according to the emergency services.
