Australia's prime minister says unarmed Australian police will be sent to the Malaysian airliner's crash site in rebel-held territory in eastern Ukraine as part of a Dutch-led police force to secure the area and help recover victims' remains.

Prime Minister Tony Abbott said Sunday that by using unarmed police, Ukraine's Parliament will not need to ratify the deployment as it would if the security force were to be armed.

Australian Federal Police Commissioner Tony Negus said 11 Australian police will initially be sent Monday into the debris field, which covers 50 square kilometers (20 square miles). He said Dutch police also will be unarmed.

The pro-Russia separatists have been blamed for shooting down Malaysia Airlines Flight 17 with a surface-to-air missile on July 17, killing all 298 people aboard.
