At least six people were Wednesday shot dead at Bula Tawakal village in Kunaso area, Garissa County, in new inter-clan clashes.
Police said the deceased were ambushed and killed by unknown gunmen while they were inside a Toyota Probox car.
The six included five students and their driver.
Tension remained high amid fears of retaliation from the affected group.
Locals said the victims were heading home from the school holidays when they were shot at.
North Eastern Regional Commissioner John Otieno said the attack is suspected to be payback after another person from the rival clan was also murdered.
“The victims were asked to identify themselves before they were shot at close range. All the deceased are from the same clan,” Otieno said.
He added that one suspect was arrested and is aiding with investigations.
He added that at least 10 people from either clan have been killed in the inter-clan clashes said to have been caused by a longstanding land scuffle.
Their bodies were later taken to tawakal cemetery for burial in accordance with Muslim rites.
