Donetsk airport: Ukraine's coveted prize
- Published
Donetsk airport has been the focus of heavy fighting for months as pro-Russian separatists try to seize it from Ukrainian government forces.
The airport is strategically important. Government forces have now abandoned the main part of it, from where they have been able to shell rebel positions inside nearby Donetsk - the largest city held by the militants.
Its capture could help the rebels to resupply - allowing munitions, hardware and manpower to be airlifted into the conflict zone.
But its significance is as much symbolic as it is practical. It has long been viewed in Kiev as an emblem of "Ukrainian fighting spirit".
Ukrainian troops defending the airport were called "cyborgs" for their toughness in repulsing constant attacks, and for many they symbolised a new Ukrainian army.
Social media users say the destruction of the airport looks like Stalingrad, the Russian city reduced to ruins in World War Two.
Satellite photos taken before the fighting and drone images taken last week offer a stark comparison.
'Cyborgs'
Nickname given to Ukrainian soldiers defending Donetsk airport after May 2014
Included regular army soldiers and volunteer fighters
Treated as heroes by many Ukrainians
Received many of their supplies from Ukraine's volunteer movement. President Petro Poroshenko himself donated some night-vision goggles
Reality of the soldiers' lives was grim - they took to social media to describe cold, dark and dangerous conditions
The Sergey Prokofiev International Airport was built ahead of the Euro 2012 football championships co-hosted by Ukraine and Poland.
It was estimated to have cost around $860m (£537m; €685m).
Images on its website, external still show a gleaming glass terminal, smiling faces and spotless waiting lounges.
Latest footage shows the extent of the destruction, with barely the shell of the building remaining.
Some experts have pointed out that the runway could still be used for flying in supplies, which is proving difficult for the rebels. But the airport's infrastructure is otherwise completely destroyed.
The separatists have been trying to capture the airport since May, allegedly with backing from the Russian military.
They view the airport as part of their capital and, as long as it remained in government hands, a bridgehead for a potential Ukrainian offensive.
"Ukraine's control of Donetsk International Airport not only ensures Ukrainian presence on the outskirts of the city, but also might prove crucial in preventing the spread of instability to other areas of Ukraine," warned Euromaidan, Ukraine's pro-Europe protest group, in October 2014., external
"A pro-Russian territory with an international airport of Donetsk's size would be a valuable asset for the territory's smuggling capabilities... de-stabilising other parts of Ukraine because of the unchecked flow of illicit weapons, drugs, and fighters."
Dr Mark Galeotti, Clinical Professor of Global Affairs at New York University, highlighted the combination of both strategic and symbolic significance in a January blog post., external
"Kiev's forces have, to be charitable, a mixed record in fighting this conflict," he says.
"For them to have lost the airport, that advance intrusion into the heart of the rebellion, would have been a serious blow to their morale and the credibility of the government."
