Rome's EUR district to become security 'red zone' for global summit this weekend.

Rome security chiefs will seal off a 10-square kilometre area of the capital's EUR district ahead of the Group of 20 Leaders' Summit taking place at the Nuvola Congress Centre on 30-31 October.

The two-day event, the culmination of a series of talks held during Italy's presidency of the G20, will see the heads of the world's wealthiest nations converge in Rome to discuss climate change, covid-19 and the post-pandemic global recovery.

The Rome summit is seen as critically important as it comes just before the United Nations COP26 climate change conference which begins in Glasgow on 31 October.
