At least three people were killed in heavy fighting that erupted in the east Ukrainian city of Donetsk Monday between insurgents and the government troops.
Intensive gunfire and blasts were heard near the airport and railway station in the northwest of the insurgent-controlled city, where local residents were fleeing the battle zone.
At least three people were killed and another wounded in the latest fighting, Xinhua cited the Interfax news agency as quoting health authorities in Donetsk.
The clashes flared up as an international investigation team arrived in Ukraine's east to probe the crash of a Malaysia Airlines flight last week.
Malaysia Airlines flight MH17, while flying from Amsterdam to Kuala Lumpur, crashed Thursday afternoon in the conflict-hit Donetsk region in eastern Ukraine killing all 283 passengers and 15 crew on board.
According to reports, the indications are that the Boeing 777 crashed after being hit by a missile. US President Barack Obama said that initial investigations showed that the missile was fired from an area in Ukraine controlled by anti-Kiev militants.
