The annual meeting of the United Nations General Assembly, which begins today in New York, usually involves a long convoy of limousines on the streets of Manhattan as world leaders and their entourages congregate to discuss the world's problems.
But even as the UN marks its 75th birthday, one of the world's biggest problems right now - the Covid-19 pandemic - means it has had to resort to "digital diplomacy" in its biggest annual event.
No presidents or prime ministers will be physically present and only a small number of representatives from the UN's 193 members - those already in the US - will be allowed to gather in the Assembly Hall.
