A man stabbed his wife in the cheek, striking a bone, in a family dispute at Khorof Harar, Wajir county, on Wednesday evening.
Doctors at Wajir General Hospital said they could not remove the knife from Fatuma Ibrahim's cheek as this would likely result in complications.
They said chances were that the complications would endanger the life of the 32-year-old woman stabbed by her husband Mohamed Deeq.
Fatuma will be flown to Nairobi by Amref flying Doctors for treatment.
In an attempt at mediation before the stabbing, Deeq's brother had confiscated knives and gone to a police station to seek assistance.
The police and medics secured Ibrahim an ambulance in which she was rushed to the hospital.
The mother of four is scheduled to be airlifted to Nairobi for an operation at Kenyatta National Hospital.
Women who turned up in large numbers in Ibrahim's support lampooned the government for ignoring their rights.
"The rights of women must be upheld to prevent attacks by these beasts. We want the government to be serious about gender-based violence," said one identified as Sahara Keynan.
Wajir East OCPD Benson Makumbi said Deeq was placed in police custody and will be charged with causing grievous bodily harm on Friday.
