Russian President Vladimir Putin has been spotted travelling to the Pacific Coast in an armoured limo ahead of his highly anticipated summit with Donald Trump in Alaska, with a massive convoy sweeping through sealed-off roads.

Footage shows a long line of black vehicles speeding along a road, flanked by flashing police cars and trailed by what appears to be an ambulance.

The tight security comes as Putin prepares to sit down with Trump on Friday for their first face-to-face meeting since 2018.

The talks, set against the backdrop of the ongoing war in Ukraine, are expected to focus on finding a path toward a ceasefire.

Trump extended the invitation at the Russian leader's suggestion, but the US president has since been defensive and warned that the meeting could be over within minutes if Putin does not compromise.
