Nigerian students inhale tear gas after drill blunder
When the school authorities were told to close for the day due to the event, some parents hurriedly picked up their children.
According to local media, during a morning drill in Nigeria's southwest Osun State, tear gas canisters shot by anti-riot police caused more than 30 pupils to become unwell and require hospitalization.
In the city of Osogbo, it was going on directly across from Fakunle Comprehensive School, but the fumes drifted over to the campus.
According to reports, after losing consciousness, the secondary school kids were taken immediately for emergency medical care to two different hospitals.
Yemisi Opalola, a spokeswoman for the Osun police, expressed regret for the occurrence and promised that the officers will make the "necessary adjustments" to avoid a repeat.
