Nigeria's rainy season brings devastating floods
Over 300 people in Nigeria have died and 100,000 have lost their homes in recent flooding. Emergency services say it is the country's worst flooding since 2012.
Anambra is one of the 29 states out of 36 in Nigeria to have experienced flooding so far this year. At least half a million people have been affected due to injury, loss of property or other forms of material wealth, such as livestock and land.
Such boat accidents occur frequently in Nigeria due to lax safety standards, speeding, overcrowding and limited regard for maritime traffic rules.
Nigeria is struggling to cope with food shortages, famine and hunger brought on by myriad crises resulting from COVID-19 and Russia's war of aggression against Ukraine.
Farmlands and crops have also been ravaged by the flooding, placing further stress on food supplies.
