The oil crisis of 1973

In October 1973, Arab nations protested the American support of Israel in its war against Egypt and Syria by slashing oil production, causing prices to sky rocket. Dr Fadhil Chalabi was deputy secretary general of Opec (Organisation of the Petroleum Exporting Countries). In 2014 he spoke to Alex Last about the embargo. (Picture: Empty gas pump in 1973.
