PM considers options on securing MH17 crash site

PRIME Minister Tony Abbott is considering a range of options for Australian involvement in an operation to secure the crash site of MH17 in eastern Ukraine.

Mr Abbott today told reporters in Canberra he had had discussions with "a number of leaders", who had backed the proposal to secure the site to ensure a successful investigation.

While he did not say whether such an operation would directly involve Australian troops, he said he also had spoken to several "senior officials" regarding the options to secure the site.

But Mr Abbott did say any operation to secure the site, in disputed territory controlled by Russian-linked rebel forces, would be completed "absolutely" in line with the United Nations Security Council resolution approved earlier this week.

The area, he said, was about 50km square, and included not just farming property but also villages, indicating a multi-national force would need to "cordon off" the area to preserve the site for investigation.

He also confirmed a train carrying most bodies had arrived in Kirkov, but it was unclear how many actual victims were delivered.
