(CNN) – A week after Malaysia Airlines Flight 17 crashed in eastern Ukraine, the crash site, with wreckage spreading out for miles, is still not secured.
Australia's Prime Minister Tony Abbott said he has sent 50 Australian police to London so that they can be deployed to help lock down the crash site in Ukraine. Abbott says he realizes the rebel-controlled area could be dangerous, but that he has Russian President Vladimir Putin's support.
Incredibly, investigators on site have discovered a huge new piece of wreckage.
"It was a jaw dropping experience, we found this big piece of fuselage," said Michael Bociurkiw, the spokesman for the Organization for Security and Co-operation in Europe, the group monitoring the crash scene.
The wreckage was largely intact, and was something people would recognize as a commercial airliner - the windows were still in tact.
"And sadly, as well, for the second day in a row, we did find signs of human remains again today," said Bociurkiw.
