Australian Prime Minister Tony Abbott says he is determined to secure a one-on-one meeting soon with Russian President Vladimir Putin to demand full cooperation in the investigation into the shooting down of a Malaysian airliner over Ukraine.

In a joint news conference with Abbott on Thursday, Dutch Prime Minister Mark Rutte revealed that investigators had retrieved more human remains this week from the rebel-held site where Malaysia Airlines Flight 17 was shot down on July 17 with the loss of 298 lives, mostly Dutch.

He had recently announced that a team reached the spot where the plane's wreckage is scattered and retrieved an unspecified number of human remains.

The tragedy was at the top of the agenda in meetings on Thursday between Rutte, Abbott and the Australian Cabinet.
