A ferry that sank in the Congo killing up to 200 people was overloaded by four times its safe capacity.

Survivors who swam to safety after their overcrowded boat capsized on a river in the Democratic Republic of Congo said fishermen refused to help drowning passengers, instead looting the goods aboard the burning vessel and beating people with oars.

Two boats capsized in separate incidents on Congo’s vast rivers, leaving 70 people dead and 200 others missing.
