Switzerland has frozen more than $1 billion in assets linked to current and former North African dictators. More than $450-million of the assets are believed to have been illegally obtained by former Egyptian president Hosni Mubarak and his acolytes. Another $398 million was linked to Libya’s Muammar Gaddafi. Some $66 million was controlled by Tunisia’s former dictator, Zine al-Abidine Ben Ali. Switzerland agreed to freeze suspect funds in February, but only announced the figure today. A government official told the BBC that no alternate regime has provided enough evidence for the money to be returned.
