Officials have closed a school in Dabaab after al-Shabaab militants launched an attack early on Tuesday.
Garissa County Commissioner Mweru Mwangi said Saretho Boarding Primary School was closed indefinitely.
Four civilians and two suspected militants were killed around 2.30 am on Tuesday morning after attackers attempted to destroy a Safaricom mast in Saretho area.
The headteacher of Saretho Boarding Primary School said the attack happened near teachers' quarters.
An official statement from police said a teacher and a child were among the innocent lives lost in the pre-dawn attack.
The school was closed by the County Education Director Khalif Issack immediately after the incident.
“We are requesting parents of children who did not report to school to let them stay at home. The school is closed until normalcy returns,” said Mr Issack.
