Putin warns of second war in Europe; Russia claims Ukraine pumping Moldovan border with arms

Russia has made a sensational allegation as the war in Ukraine completes a year. Russia has accused Ukraine of waging a false-flag operation in its neighbouring nation Moldova. Russia claims that Ukraine is planning to wage a war in the tiny European nation's breakaway region - Transnistria, where the Russian peacekeeping mission is in force. The Russian defence ministry said it has proof of Ukrainian military build-up along the border. It also warned that Russia is ready to respond to any kind of provocation. The Moldovan government, which hopes to join the European Union, has refuted Russia's claims. Watch this video to find out what the controversy is all about.
