Buhari in a statement issued on Friday by his spokesman Garba Shehu, commiserated with the government and people of the Niger Republic, describing the tragedy as extremely terrific.
“On behalf of the government and people of Nigeria, we commiserate with our brotherly neighbours on this tragic loss,” a message to President Mohammed Bazoum read.
“Our thoughts and prayers are with the victims, families and communities affected by this unfortunate incident, wishing quick recovery to those who were injured.”
No fewer than 20 children died on April 13 after they were trapped in a fire at a school in the country’s capital.
According to eyewitnesses, the fire started late on Tuesday afternoon when the children were in lessons, many in straw-hut classrooms.
The flames blocked the school gate, so most pupils had to escape over a wall, said a teacher’s union official quoted by Reuters.
Most of those who did not manage to escape were attending the school’s nursery, officials say.
