 Secretary of State John Kerry is in London for key talks on Ukraine 
with his Russian counterpart Sergei Lavrov, as a disputed referendum in 
Crimea looms on Sunday.
Mr Kerry is expected to warn Mr Lavrov that the referendum 
and Russia's military intervention in Crimea could trigger concerted US 
and EU sanctions.
He has warned of "very serious steps" if Russia annexes the region.
Russia insisted at the UN on Thursday it did "not want war" with Ukraine.
During an emergency meeting of the Security Council, Moscow's
 ambassador to the UN Vitaly Churkin defended the right of Crimea, which
 is predominantly ethnic Russian, to decide whether or not to join the 
Russian Federation.
Russia's military intervention followed the fall of Ukraine's pro-Moscow President Viktor Yanukovych on 22 February.Ukrainian and Russian press reaction 
The Kerry-Lavrov talks and Crimean referendum dominate the 
media, with Ukrainian commentators gloomy while Russian papers scent 
victory. 
Leonid Kravchuk, Ukraine's first president, calls on the 
country to "immediately launch a bid to join Nato" and seek 
international peacekeepers, according to Den daily.
Pundit Stepan Havrysh writes in Hazeta that the referendum 
"will be rigged", as the "illegal Crimean authorities have simply 
decided to join Russia".
In Russia, Nezavisimaya Gazeta sees nothing to discuss. "Even
 the hottest heads in Washington now admit that the Crimea question is 
completely settled, a fait accompli".
Moskovsky Komsomolets tabloid draws historical parallels. 
"Serious people are trying to scare us by asking 'Do you realize how 
much it will cost to annex Crimea?' Well, how much did it cost Britain 
to send its navy to war with Argentina for the completely useless 
Falklands?"
Pro-government Izvestia sees the start of a "new ideology of 
reclaiming Russian lands", for which President Putin will be "forgiven 
everything and anything".
Russian historian Dmitry Shusharin is not so sure. "Crimea is a modern-day Pearl Harbour," he writes in the Ukrainian daily Den.
