All 298 people aboard Malaysia Airlines Flight 17 - most of them Dutch citizens - were killed when the plane was shot down on July 17. U.S. officials say the Boeing 777 was probably shot down by a missile, most likely by accident.
Australian Prime Minister Tony Abbott, who says he fears some remains will never be recovered unless security is tightened, has proposed a multinational force mounted by countries such as Australia, the Netherlands and Malaysia that lost citizens in the disaster.
To that end, Abbott said Thursday he had dispatched 50 police officers to London to be ready to join any organization which may result.
Foreign Minister Julie Bishop was traveling with her Dutch counterpart Frans Timmermans to Kiev to seek an agreement with the Ukraine government to allow international police to secure the wreckage, Abbott said.
Details including which countries would contribute and whether officers would be armed and protected by international troops were yet to be agreed, Abbott said.
On Monday, the U.N. Security Council unanimously approved a resolution proposed by Australia demanding that rebels cooperate with an independent investigation and allow all remaining bodies to be recovered.
The first bodies remains arrived in the Netherlands on Wednesday and were met by Dutch King Willem-Alexander, Queen Maxima and hundreds of relatives.
Ukraine's government said 51 containers of bodies and body parts had been cleared for Thursday's flights. At least 200 bodies were aboard the train that brought them from the crash site to Kharkiv earlier this week.
Dutch police spokesman Ed Kraszewski told The Associated Press that a team of 25 forensic experts and dozens of support staff began working to identify remains Wednesday evening at a military barracks on the outskirts of the central city of Hilversum.
Staff will "examine the bodies, describe the bodies, take dental information, DNA and put all the information together in the computer and compare this information with the information they gathered from the families in the last days," Kraszewski said in a telephone interview. "Then we have to see if there is a match."
Meanwhile, police and traffic authorities appealed to the public not to stop on the highway as a convoy of hearses passes by Thursday on its way from Eindhoven Air Base to Hilversum.
On Wednesday, the convoy of hearses passed through roads lined with thousands of members of the public, who applauded, threw flowers or stood in silence as the cars drove by.
The Dutch Foreign Ministry said Thursday that the number of Dutch victims had risen by one to 194, taking into account a woman with joint German and Dutch nationalities who earlier had been listed as German.
Senior U.S. intelligence officials said Tuesday that Russia was responsible for "creating the conditions" that led to the crash, but offered no evidence of direct Russian government involvement.
The officials said the plane was likely shot down by an SA-11 surface-to-air missile fired by Russian-backed separatists in eastern Ukraine. The U.S. officials cited intercepts, satellite photos and social media postings by separatists, some of which have been authenticated by U.S. experts.
Russia on Thursday brushed off the accusations. Deputy Defense Minister Anatoly Antonov said in a video statement that if the U.S. officials indeed had the proof the plane shot down by a missile launched from the rebel-held territory, "how come they have not been made public?"
Pro-Russian rebels and Ukrainian government troops have been fighting for more than three months, leaving at least 400 dead and displacing tens of thousands.
Ukrainian forces are trying to ride the momentum of taking the strategic city Slovyansk on July 5 which was in rebel hands for more than two months. Government forces are now closing in on Donetsk, where insurgents regrouped after leaving Slovyansk, and are trying to cut off supply routes to rebels based in the neighboring Luhansk region.
