Mirgayas Shirinskiy, the Russian ambassador to Sudan, was found dead in his swimming pool on Wednesday. The cause of death was drowning, according to local police, and a spokesman said Mr Shirinskiy was known to have high blood pressure.
What makes the case more intriguing however, is that Mr Shirinskiy is now the fourth Russian ambassador to die on the job in just eight months.
Assassinations of Russian diplomats is nothing new – in fact, it might be regarded as one of the most dangerous jobs in the world.
Remaining on the right side of both local warlords, military chiefs and security agencies, as well as pleasing the Putin regime is a high-wire balancing act.
