Mombasa Governor Ali Hassan Joho on Tuesday took to Twitter to convey his condolences to the family of French diplomat Jean Pierre Tutin.
Reports indicate that Tutin died in Uganda after a gorilla tracking expedition at a National Park.
According to Christine Posi, 59, another French national who was part of the team, their colleague developed a strange illness soon after returning from Bwindi Impenetrable National Park where they had spent time together tracking gorillas.
The region's police boss Elly Maate stated that investigations would be opened into the incident to find the root cause of Tutin's death.
According to the Daily Monitor, he is the second tourist to die in Kigezi Sub-region in this month alone, with the recent being a British national who collapsed and died on April 7 on his way to tour the Batwa settlement in Butanda Sub County, Kabale District.
Joho described the deceased as a great friend who worked with him in revamping Mombasa County.
"It is with deep shock and sorrow that I have received the news of the sudden demise of my friend Mr. Jean Pierre TUTIN.
"Until his demise, Mr. TUTIN served as the Head of Cooperation and Cultural Affairs.
"Together we had laid a project that aimed at revamping the Mombasa tourism sector through the conception of cultural products and scenography of this great city.
"We have lost a brilliant mind who had passion for the preservation of our culture," he wrote.
