I want to know the answer to the following question:
Along with Libya, Morocco, Tunisia and Algeria, who was a founding member of the Arab Maghreb Union?
All the background I'm provided with is that "Many African states opposed the UN sanctions, with Mandela criticising them on a visit to Gaddafi in October 1997, when he praised Libya for its work in fighting apartheid and awarded Gaddafi the Order of Good Hope.". Is that enough to answer the question?
