Political transitions began in Libya in 2011, with the overthrow of Colonel Gaddafi. Protests, unrest and violence plagued the country throughout 2012 and 2013, bringing the country to a standstill. Protesters have targeted the oil and gas industry, Libya's only real source of revenue. Oil production levels hit a post-civil war low of 130,000 b/d in September 2013 down from 1.6 million b/d and exports have been greatly reduced. The downturn in supply has significantly impacted Libya's domestic market too.
