TRIPOLI, Libya -- A global outcry has continued to grow after a CNN exclusive investigation revealed African migrants are being sold as slaves in Libya.
Critics say that European countries share some of the blame since they rely on Libya to prevent migrants from corssing the Mediterranean Sea into the European Union.
The Libyan government, backed by the U.N., says it is investigating. Protesters across Europe are demanding change. In London, protesters filled the yard in front of the Libyan embassy as they held signs and chanted.
