France is to hold a day of national mourning after Cyclone Chido devastated its Indian Ocean territory of Mayotte earlier this month. French President Emmanuel Macron called for the nationwide remembrance during his visit to the island last week - where he was jeered by some islanders who criticised the slow delivery of aid.

French President Emmanuel Macron was due on Friday to visit shantytowns in Mayotte ravaged by Cyclone Chido on the second day of a visit where he has faced calls to speed up relief to the Indian Ocean archipelago.

"Mayotte is demolished," an airport security agent told President Emmanuel Macron as he arrived in the remote French territory five days after Cyclone Chido.
