'Damage control' is how many are describing the Trump administration's handling of a leak of highly sensitive information. Eighteen senior officials -- including the CIA director, the defence secretary, the national security adviser and the vice president -- were part of an online group chat that's gone viral. An American journalist was also on that chat -- and was made privy to US plans to strike Houthi positions in Yemen – before they happened. The breach is raising questions about the handling of military intelligence and top-secret information. So, will there be consequences beyond Washington? And how will long-time allies in Europe respond to being criticised in the chat?
