American officials are rushing to finalize details ahead of Friday’s summit talks between Presidents Donald Trump and Vladimir Putin in Alaska, with both logistical and geopolitical issues still unsettled four days ahead of the momentous sit-down.

On Friday evening, Trump posted on his social media site Truth Social that a "highly anticipated meeting" between him and Putin would take place on 15 August in the "great state of Alaska". "Further details to follow," he said. Trump had said the meeting location would be "a very popular one for a number of reasons".
