(Bloomberg) -- Kenyan security forces ended an attack on an office complex in the capital by suspected Islamist militants that left 14 people dead, President Uhuru Kenyatta said.

All of the assailants were killed, Kenyatta said in a televised address Wednesday in Nairobi.

“We will seek out every person that was involved in the planning, funding and execution of this heinous act,” Kenyatta said.
