The government is appealing to residents of Isiolo county to remain cautious as teams continue to work to fully extinguish remaining wildfires.
Interior PS Raymond Omollo said in an update Monday evening that the fire, which started a week ago, has affected an estimated 300,000 acres of dry grassland.
He said efforts are ongoing to smother the fires but strong winds and hot weather conditions were posing a significant challenge to the teams on the ground.
"Fortunately, no casualties have been reported, and no damage has occurred to human settlements, livestock, or wildlife," Omollo said.
The fire first broke out at the Malkagalla area a week ago in Merti but had by Monday spread to Bassa, Matarba and Sericho locations where over 190,000 acres of grassland have been reduced to ashes.
Omollo said a multi-agency team comprising of National Government Administrative Officers, the National Police Service, Kenya Wildlife Service, Red Cross, the County Government of Isiolo and local community members, spent the better part of Sunday containing the spread of the fire and preventing further destruction.
"However, small pockets of fire remain in Sericho and Malkagada, where teams are still working to put them out," he said.
The fires were allegedly started by herdsmen who were attempting to rid the area of tick infestation.
On Monday, local elders called for urgent intervention from the county and national government amid fears that the inferno could result in loss of livestock and human life if quick interventions were not taken to stop its spread into human settlements.
"Let's also see helicopters appearing for us to feel we are also cared for by government that can save its citizens," an elder said.
The fire is consuming vital grazing areas for herders in the county that is home to communities that practice livestock rearing as their primary economic activity.
