Russia tells S. Sudan to find UN chopper gunmen

MOSCOW (AFP) - Russia urged South Sudan on Saturday to punish those responsible for shooting down a UN peacekeeping helicopter and killing all four Russian crew members aboard, in an attack condemned by the international community.

"We call on the government of South Sudan to carry out the necessary investigation, punish the guilty and take every measure to guarantee that this never happens again," the foreign ministry said in a statement on its website after Friday's incident.

A South Sudan military spokesman said troops fired anti-aircraft guns at the Russian Mi-8 believing it was a rebel helicopter carrying weapons to anti-government forces in the world's newest country.

The United Nations said the aircraft was hit while on a "reconnaissance flight" over the Likuangole district of the eastern Jonglei state.

"The tragic event in this African country raises with new urgency the question of the security of UN peacekeeping missions," the Russian ministry said, attributing the helicopter downing to "blunders."

"The governments of countries that accept missions and carry the main responsibility for the security of UN peacekeepers must approach this problem with all seriousness and recognise all the possible consequences of blunders," it said.

It cited South Sudan officials as saying the helicopter was downed "despite the fact that the UN mission informed the local command about the planned flight as usual."

"The mission was guaranteed complete safety," the ministry said.

Russian television named the men who died as commander Sergei Ilyin, second pilot Alfir Abrarov, flight engineer Sergei Yegorov and cabin attendant and radio operator Nikolai Shpanov.

UN leader Ban Ki-moon, as well as the UN Security Council and the United States had vehemently condemned the attack.

He said Friday it was a "clearly marked" UN aircraft and demanded that those responsible be brought to account.

The European Union's foreign policy chief Catherine Ashton also said in a statement Saturday that she "deplores" the attack and "calls on the government of South Sudan to give full cooperation in the investigation of this very serious incident".

Jongeli state has been stricken by ethnic strife since South Sudan became independent from Khartoum in July last year, becoming a base for rebellion against the new government.

It was a frontline state in four decades of near continuous civil war between South Sudan and the Khartoum government up to 2005 that left at least two million people dead.

Likuangole itself has also been at the centre of battles between rival tribes that have left thousands of people dead over the past year.

Pilots from the ex-Soviet Union are in demand in Africa because they know how to fly Soviet aircraft, while the low salaries for pilots in Russian regional airlines give them an incentive to work abroad even in difficult conditions.

The Mi-8 helicopter is a hardy workhorse model that was developed in the 1960s and is still being made in a modified version today. It can carry up to 28 passengers or be used to transport cargo.

The downed aircraft belonged to the Nizhnevartovsk-Avia air company based in the Western Siberian town of Nizhnevartovsk.

The company was working on a contract with the United Nations, acting director Sergei Bakunin said in televised comments.

"They are fine pilots. The commander had more flight experience than the others: around 7,000 hours. He went through Afghanistan, so he had great experience," he said.

The company had been working in South Sudan since March this year when Russian troops that had been servicing flights since 2006 left the region, Russian television reported.
