New clashes in eastern Ukraine have forced the international forensics team to halt operations in part of the vast crash site of Malaysia Airlines flight MH17.
Observers had to withdraw from one village when they heard artillery fire although work is still continuing across much of the area.
MH17 went down on July 17 with the loss of all 298 passengers and crew.
The US and Ukraine say pro-Russian rebels probably shot down the jet with a missile but rebels deny the claim.
Alexander Hug, the deputy chief monitor with the Ukraine mission of the Organization for Security and Cooperation in Europe (OSCE), told AFP a visit to the village of Petropavlivka had been agreed with the rebels and Ukrainian forces.
About 70 Dutch and Australian experts are scouring a site of some 20 sq km.
A spokesman for the Dutch team said it was still focusing on searching for human remains, although security is also a key issue.
Neither the rebels nor Ukrainian forces are in full control of the site.
The Dutch team has flown in from the Netherlands two dogs trained to search for human remains and another two specialist dogs are on their way from Belgium.
The Australian team also has specialist equipment – a mini-drone fitted with a camera – but it has not yet been given permission by the rebels to fly it.
The US and Ukraine say pro-Russian rebels probably shot down the plane with a missile supplied from Russia.
The rebels say it could have been brought down by a Ukrainian fighter jet.
Most of those who died were Dutch nationals.
More than 220 coffins have now been sent back to the Netherlands.
Separately, a senior adviser to the rebels confirmed that extrajudicial killings had been carried out in eastern Ukraine “to prevent chaos”.
