President Emmanuel Macron has landed in riot-hit New Caledonia, having crossed the globe by plane from Paris in a high-profile show of support for the French Pacific archipelago wracked by deadly unrest and where Indigenous people have long sought independence from France.It was late Tuesday in Paris when he climbed aboard his presidential jet but, because of the distance and time difference, it was already Thursday morning in New Caledonia when he arrived, with unrest still simmering and his interior and defense ministers in tow.
