David Cameron: UK 'won't turn blind eye to Crimea'
David Cameron has promised the UK "will not turn a blind eye" to Russia's incursion into Crimea.
The prime minister said Moscow had to be shown that it could "not trample over" Ukraine and must not hold an "illegal" referendum on whether Crimea becomes part of Russia.
International powers will meet in London on Tuesday to work on drawing up a list of Russians who could face asset freezes and travel bans if Moscow fails to de-escalate the current crisis over Ukraine.
''Chancellor Merkel and I were clear that any attempt by Russia to legitimise an illegal referendum would require us to respond by ratcheting up the pressure further,'' Mr Cameron said.
