Russia president Vladimir Putin said it is impossible to say when the Ukraine crisis will end and it depended on the political will of Ukraine's leadership, according to Reuters citing RIA news agency.
President Vladimir Putin has said Russia will continue to provide humanitarian aid to civilians in eastern Ukraine, the Kremlin announced.
He is also reported to have ordered separatist rebels to provide a humanitarian corridor for encircled Ukrainian troops to exit.
Russian President Vladimir Putin has reportedly told German Chancellor Angela Merkel that he decided to send a humanitarian aid convoy into Ukraine because he could no longer wait.
According to the Kremlin account of the phone call, President Putin expressed "serious concern" about the military escalation in eastern Ukraine.
Russian President Vladimir Putin has told his government to prepare for retaliatory measures against the latest western sanctions, the Tass News Agency reports.
"Of course, it should be done carefully in order to support domestic producers and not hamper consumers," he was quoted as saying.
Russian President Vladimir Putin has accused the West of bullying him over the Ukraine crisis - an approach he called both "strange and unacceptable".
European foreign ministers in Brussels have drawn up new sanctions against Russia but not the economic measures supported by Britain and the US.
ITV News Diplomatic Correspondent John Ray reports from Moscow:
Russian president Vladimir Putin has urged Britain to "negotiate" the sovereignty of the Falklands Islands with Argentina, accusing the UK of a "double standard in foreign relations."
Speaking at an official dinner during a visit to Buenos Aires, Putin said: "Russia supports the need to find a solution in the dispute for the [Falkland] Islands at the negotiation table directly between Great Britain and Argentina.
"I wanted to bring attention to the words of Mrs President [Fernandez] regarding the double standard in foreign relations."
Argentina president Cristina Fernandez de Kirchner has previously accused Britain of hypocrisy in criticising Crimea's pro-Russian referendum vote yet supporting a pro-British vote in the Falklands.
She said: "I appreciate, of course, the support for our national cause [sovereignty of the Falkland Islands] which is not a uniquely Argentine cause."
Russian President Vladimir Putin discussed proposals for peace in Ukraine with the US President Barack Obama today, the Kremlin said in a statement.
Speaking on the phone, the two leaders discussed the Ukrainian military ceasefire that was declared by President Petro Poroshenko last week.
Mr Obama urged Mr Putin to support the peace plan and said Moscow would face further "costs" if it did not take steps to reduce tensions in the country, the White House said.
Barack Obama has told his Russian counterpart Vladimir Putin that he must recognise the new Ukrainian President, Petro Poroshenko in order to help de-escalate the crisis in eastern Ukraine.
According to a White House official, the US President also told Mr Putin that if Russia works with the new Ukrainian authorities there could be "openings" to reduce tensions in the region.
Deputy national security adviser Ben Rhodes added that Mr Obama had demanded "ceasing support for separatists in eastern Ukraine, and stopping the provision of arms and material across the border".
David Cameron has issued a fresh warning to Russia over Ukraine ahead of meeting president Putin tomorrow.
Speaking from Brussels at the first G7 summit without Russia for 17 years, Mr Cameron said: "The G7 should send a clear message of support to Ukraine and a united message to President Putin that he needs to engage with the Ukrainian government to find a diplomatic solution to the crisis.
"That's what I'll be saying to President Putin myself tomorrow. This is the first summit without Russia since the 1990s. And until they change course, they need to understand that they will face continuing isolation and no seat at the table."
The G7 leaders effectively expelled Russia from the annual gathering, which Mr Putin had been due to to host in Sochi, following its incursion into Crimea.
Cameron and Putin are due to meet tomorrow in Paris ahead of the D-Day 70th anniversary commemorations on Friday.
Prime Minister David Cameron will meet Russian president Vladimir Putin on Friday for face-to-face talks on the crisis in Ukraine, Downing Street said.
