GENEVA (Reuters) - The United Nations High Commissioner for Human Rights called on Friday for countries to clamp down on people smugglers and human traffickers after at least 78 migrants were killed in a shipwreck off the coast of Greece.
Witness accounts suggested between 400 and 750 people had packed a fishing boat that capsized and sank early on Wednesday morning about 50 miles (80 km) from the southern coastal town of Pylos.
