Trump calls off G20 meet with Putin over Ukraine crisis

US President Donald Trump has scrapped his long-planned meeting with Russian President Valdimir Putin, at the G20 summit over Moscow's detention of a group of Ukrainian sailors. Blaming Russia for failing to return Ukrainian ships, in a series of tweets, Trump said it would be best for all parties to cancel the meeting. Trump's decision comes as Ukrainian President, Petro Poroshenko, reached out to the NATO for security amid crisis with Russia.
