Australian and Dutch investigators have failed for a third consecutive day to reach the MH17 crash site because of fierce fighting between Ukrainian troops and pro-Russian separatists, Australian Prime Minister Tony Abbott said Tuesday.
Abbott, who met with the national security committee in Canberra, said that it was a "confused situation on the ground", Xinhua reported.
"There is fighting and it's not just the separatists, it's the Ukrainian government as well," Abbott said.
He said that both sides had made a commitment to using "their best endeavours" to get the site safe enough for the Dutch-Australian team.
"And it's high time those commitments were honoured," Abbott said.
Australian Federal Police (AFP) said the situation was too risky after they encountered shelling on approach to the crash site.
