Ukrainian troops advance on flight MH17 crash site amid fight with rebels
Ukraine said its troops had taken more territory from pro-Russian rebels near the site where Malaysia Airlines flight MH17 was brought down.

Ukraine said its troops had taken more territory from pro-Russian rebels near the site where Malaysia Airlines flight MH17 was brought down. International investigators said fighting had again prevented them reaching the crash location.
The separatists are still in control of the area where the plane was shot down but fighting in the surrounding countryside has been heavy as government forces try to drive them out.
"The Ukrainians have taken over a part of the crash site," said Vladimir Antyufeyev, the self-styled first deputy prime minister of the Donetsk People's Republic.
Ukrainian officials said two rebel-held towns had been recaptured and attempts were being made to take a village Kiev says is near the launch site of the surface-to-air missile that shot down the airliner with the loss of all 298 on board.
