By Matthew Blake and Reuters Fighting broke out near the railway station at the heart of the rebel stronghold of Donetsk on Monday in what separatists said was an attempt by government forces to seize back the east Ukrainian city. The government in Kiev denied sending the regular army into the centre of Donetsk, which the separatists captured in April, but said small 'self-organised' pro-Ukrainian groups were fighting the pro-Russian rebels in the city. Four people were killed in clashes near the railway station and close to the airport outside Donetsk, local health officials said in the industrial city which was home to about one million people before many fled the fighting in the region.
