Russian president Vladimir Putin called President Barack Obama to talk about the ongoing conflict between Russia and Ukraine. He called inquiring about how to peacefully resolve the conflict. Obama received Putin's call when he was in Saudi Arabia.
According to NY Times, Ukraine's border had troops building up, and Putin's call to Obama was unexpected. They agreed to send their chief diplomats to discuss how to prevent this crisis from getting worse.
This has commonly been seen as the biggest conflict since the end of the Cold War, but it remains unknown whether Putin is genuinely interested in reaching a settlement with Ukraine.
According to BBC News, Obama urged Putin to avoid building up more troops on the Russian border. The U.S. created a proposal for Russian troops to return to their bases and to protect Russian speakers' rights in Crimea.
