Ambassador Mirgayas Shirinsky was found dead in his pool on Wednesday night according to the Sudanese Ministry of Foreign Affairs.

:: Russia’s ambassador to Sudan, Mirgayas Shirinsky, was found dead at his Khartoum residence on Wednesday, the Sudanese foreign ministry said.

“The Russian ambassador died this evening at his Khartoum residence,” the ministry said, without giving a cause of death.

An initial investigation had ruled out “foul play” as the cause of the ambassador’s death, which was confirmed by Moscow, AFP reported.

The ambassador, who was born in 1954, “died while he was swimming in his pool at his house”, the officer said.

A diplomatic source also confimed that the Russian envoy in his 60s was found dead in the swimming pool of his residence in north Khartoum.

“We grieve to announce that on August 23 in Khartoum the Russian ambassador to Sudan, M. Shirinsky, died,” Russia’s RIA Novosti state news agency reported, citing the foreign ministry in Moscow.

“As soon as we receive detailed information from the Russian embassy staff in Khartoum, we will give information on the circumstances of the death of our colleague,” it said.

The Sudanese Ministry of Foreign Affairs said in their statement that Mr Shirinsky has “taken true steps to better the relationship between Khartoum and Moscow”.

Police spokesman Omar al-Mokhtar said Sudanese officials had now taken Shirinsky’s body to a morgue in the capital. “We are now waiting for instructions from the Russian foreign ministry.”

A fluent Arabic and English speaker, Shirinsky had been a diplomat since 1977, the embassy said on its website.

He studied at Moscow Institute of International Relations and had been appointed as ambassador to Khartoum in 2013, having previously served as ambassador to Rwanda.

Shirinsky’s long diplomatic career also included postings in Egypt, Saudi Arabia and Yemen.

This is the ninth death of a Russian diplomat within a year.
