JOHANNESBURG—Honking and drumming, tens of thousands of people protested Saturday in Mauritius over the government’s slow response to an oil spill from a grounded Japanese ship and the alarming discovery of dozens of dead dolphins in recent days.
The protesters displayed signs such as “You have no shame“ and “I’ve seen better Cabinets at IKEA.” “Inaction,” one protester scrawled on an inflatable dolphin held above the crowd.
