Some 70 Dutch and Australian police investigators spent a third day trawling through wreckage for more unrecovered remains of the 298 people killed when the Malaysian passenger jet was blown out of the sky over separatist territory almost three weeks ago.
After days of fierce fighting prevented experts reaching the scene of the disaster, the Dutch-led probe has now bulked up to near full-strength with sniffer dogs and refrigerated ambulance vans brought in as they scramble to make up for lost time.
Around the rebel-held location the boom of shellfire nearby -- which forced a small crew of investigators to abandon part of the site yesterday -- shows that the conflict that has claimed over 1,150 lives since mid-April continues to tear apart the former Soviet state.
The United States accuses insurgents of blowing the airliner out of the sky on July 17 with a surface-to-air missile likely supplied by Russia, while Moscow and the rebels have pointed the finger at the Ukrainian military.
Government forces have made major gains over the past month and say they are getting close to cutting off the main rebel stronghold of Donetsk from the Russian border and a second insurgent bastion of Lugansk.
Kiev's military top brass has promised to stamp out the insurgency in the near future but analysts warn the fighting could drag on as rebels have holed up in major cities and pledged to battle to the death.
