A Mexican Air Force plane carrying the remains arrived at near midnight Saturday in what the Foreign Relations Department called an "unprecedented" effort.
The urns were taken from the plane and placed on a table adorned with white flowers for a brief ceremony.

Roman Catholic Cardinal Timothy Dolan, the archbishop of New York, celebrated a Mass for the coronavirus victims on Saturday at St. Patrick's Cathedral, blessing the ashes.
