Fierce fighting rages on for control of key airport in Eastern Ukraine
Donetsk airport, thought to be strategically important for both sides in the conflict, has seen increasingly heavy fighting around it for the past few days. Separatists claimed to have controlled sections of the airport, but the government says they have been pushed back and regained control of all terminals.
An Associated Press reporter said that tanks belonging to the separatists were seen firing shells at the airport's main terminal, where government troops are holed up.
A fragile ceasefire declared on 5 September looks increasingly under threat of collapsing.
