DONETSK, Ukraine, July 21 (Xinhua) -- At least three people were killed as heavy fighting erupted in the east Ukrainian city of Donetsk on 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 one wounded in the latest fighting, the Interfax news agency quoted health authorities in Donetsk as saying.
The clashes flared up as an international investigation team has arrived in Ukraine's east to probe the crash of a Malaysia Airlines flight last week.
The Boeing 777 passenger plane en route from Amsterdam to Kuala Lumpur crashed near Donetsk in eastern Ukraine on Thursday, killing all 298 people on board.
