Three acclaimed chefs were among a group of four people killed in a traffic accident in a highland area of southern Peru.

The SUV in which the chefs - Peru's Ivan Kisic and Lorena Valdivia and Australia's Jason Nanka - were riding slammed into a truck that had just collided with a public-transport vehicle.

Police commander Victor Ccanahuire on Friday confirmed the deaths of Kisic, a Peru Brand gastronomic ambassador; Valdivia and Nanka, a couple who owned a restaurant in Lima; and Maria Huamani, who was apparently a chef in the Ayacucho region.

Another three people were injured and taken to a local hospital, he said.

According to the El Comercio daily, the chefs had been invited to Ayacucho by a fruit producers' cooperative.
