LONDON - Saif al Islam, the son of Libya's leader Muammar Gaddafi, said on Thursday there was no need for any foreign role in ending Libya's crisis when asked about a mediation offer by Venezuela.Saif said in an interview with Sky News that he had not heard about the offer by Venezuelan President Hugo Chavez, but added: "We have to say thank you ... but we are able and capable enough to solve our issues by our own people ... ourselves. There is no need for any foreign intervention.""...They are our friends, we respect them, we like them, but they are far away. They have no idea about Libya. Libya is in the Middle East and North Africa. Venezuela is in Central America. We appreciate this."
