More human remains have been found and wreckage uncovered during a visit of three Australian officials to the MH17 site in eastern Ukraine.

Prime Minister Tony Abbott today inspected the Australian Federal Police operations room in Canberra where Operation Bring Them Home is being co-ordinated.

“Previously undiscovered wreckage has been found and I regret to say more human remains have been found and we expect that further remains will be found in the days ahead,” Mr Abbott said.

He said this made it more important than ever to properly secure the site.

Currently 90 AFP officers have been pre-deployed to Europe under a Dutch-led investigation.

Australia is close to finalising an agreement with the Ukraine for the deployment of Australian police, some of whom will be armed, to the investigation.

A further 100 AFP officers are to be sent on Friday.
