David Cameron has warned the Russian president EU leaders are willing to cooperate and "bring further action" against the country over the MH17 plane crash in Ukraine.
The prime minister said Vladimir Putin should "do everything in his power to make these separatists open up that site so there can be a proper investigation".
He said the Russian president should stop troops and weapons crossing the border and there should be respect for "Ukrainian territorial integrity".
Mr Cameron added that "if you give separatists advanced weapons systems, you can have a catastrophe like this".
