Several children have died during a stampede at a holiday funfair in south-western Nigeria.

The incident happened on Wednesday (local time) at the Islamic High School in Basorun, Oyo State, near the economic hub of Lagos.

Security forces on the scene had arrested the event organisers, state governor Seyi Makinde said.

“Earlier today, an incident occurred in Islamic High School Basorun, the venue of an event organised for families. Sadly, a stampede at the venue has led to multiple loss of lives and injuries. This is a very sad day,” Makinde said.

“We sympathise with the parents whose joy has suddenly been turned to mourning due to these deaths.”

Nigeria’s national emergency services said it had sent a team to help provide assistance to the victims.

Children injured at the venue were taken to local hospitals, where parents were asked to check for missing people.

Video footage that appeared to be from the scene showed a large crowd of mostly children looking on as some children were being carried away from an open field.

Local media identified the event organisers as the Women In Need Of Guidance and Support Foundation, which held a similar event for children in 2023.

The group was preparing to host up to 5000 young people at this year’s event, the Oyo-based Agidigbo FM radio station reported on Tuesday, citing the organisers who had featured on its program. Children “will win exciting prizes like scholarships and other bountiful gifts”, they said.

An investigation had been opened into the causes of the stampede, Makinde said, adding “anyone directly or remotely involved in this disaster will be held accountable”.
