Panamanian President Jose Raul Mulino celebrates with "joy" the 25th anniversary of the handing over of the interoceanic canal by the United States, which he says is accompanied by "sadness" for the death of former US President Jimmy Carter two days earlier, holding a minute of silence in his memory. Carter (1977-1981) signed the historic treaty with former Panamanian President Omar Torrijos (1968-1981) to transfer control of the canal from the US to Panama.
