Three siblings of the same parents, a boy and two girls, died on Sunday in a car parked in their residential quarters in Ilorin, the Kwara State capital.
The incident reportedly happened after their mother, Shade Silifat, left them to buy Indomie noodles for their school meals on Monday.
Silifat reportedly fainted when she came back to her No. 8, Boluke Line, Zango-Kulende quarters in the Ilorin metropolis and discovered what had happened.
Eyewitnesses said the incident occurred about 2 pm when the three children locked themselves in the parked car borrowed by their father from his sister within the premises of their quarters.
Their mother, who discovered their footwear outside the parked car, raised an alarm after forcing the doors of the car open.
According to Daily Post, the three children were then rushed to Olutayo Clinic, very close to their residence for medical attention.
The medical director, Dr Adeyemo, however, directed that they be taken to the University of Ilorin Teaching Hospital, Ilorin, where they were confirmed dead.
The bodies of the three siblings were later taken to a Muslim cemetery for burial according to Islamic rites.
