ABUJA, Nigeria (AP) — At least 30 people have been killed and an unspecified number of people injured in a road accident in northwest Nigeria, authorities said.

The accident occurred Sunday in Kwanar Barde in the Gezawa area of Kano state and was caused by “reckless driving” by the driver of a truck-trailer, Gov. Abba Yusuf said in a statement. He did not specify what other vehicles were involved.

Yusuf described the accident as “heartbreaking and a great loss” to the affected families and the state. He did not provide more details of the accident.

Africa’s most populous country recorded 5,421 deaths in 9,570 road accidents in 2024, according to data by the country’s Federal Road Safety Corps.

Experts say a combination of factors including a network of bad roads, lax enforcement of traffic laws and indiscipline by some drivers produce the grim statistics.

In December, boxing heavyweight champion Anthony Joshua was in a deadly car crash that injured him and killed Sina Ghami and Latif “Latz” Ayodele, two of his friends, in southwest Nigeria.

Adeniyi Mobolaji Kayode, Joshua’s driver, was charged with dangerous and reckless driving and his trial is scheduled to begin later this month.

Africa has the highest road fatality rate in the world despite having only about 3% of the world’s vehicles, mainly due to weak enforcement of road laws, poor infrastructure and widespread use of unsafe transport.
