At least 44 people have died after a ferry capsized on Lake Kariba in Zimbabwe, turning a routine journey across one of Africa’s largest reservoirs into a major rescue operation. Seventy-seven people have so far been rescued, while teams continue to search the lake for survivors and victims. The disaster has now brought renewed attention to safety on the waterway, particularly as authorities work to establish exactly how many people were aboard the ferry and what caused it to capsize.
