Killed British rancher Tristan Voorspuy.
The British government has urged Kenya to restore law and order in Laikipia after a British rancher was shot dead there.
Numerous attacks have taken place in drought-stricken Laikipia region in recent months.
Armed cattle herders searching for scarce grazing have driven tens of thousands of cattle onto private farms and ranches. At least a dozen people have been killed.
The most recent victim was Tristan Voorspuy, a British army veteran who held dual Kenyan and British citizenship and ran a company called Offbeat Safaris.
Nic Hailey, Britain's high commissioner (ambassador) to Kenya, said he had repeatedly conveyed to the Kenyan government Britain's concern over the situation in Laikipia.
"(I) continue to urge the Kenyan authorities to take all necessary steps urgently to restore law and order, and to protect life and property in the area," he said in a statement.
