The OSCE said its monitors, accompanied by Dutch and Australian experts, reached the crash site of Malaysia Airlines flight MH17 in eastern Ukraine on Thursday, two weeks after the plane came down.
"OSCE... monitors reach MH17 crash site for first time in almost week, accompanied by four Dutch, Australian experts. Used new route to access," the Organisation for Security and Cooperation in Europe posted on Twitter.
Although most of the bodies have been recovered from the site, there are still human remains and personal belongings to be secured.
The area has been inaccessible all week due to fighting between pro-Russian separatists and Ukrainian forces, who have accused rebels of placing land mines to prevent a proper investigation.
