[originaltext] Attacks by terrorists have led to a dramatic fall in tourism

Attacks by terrorists have led to a dramatic fall in tourism in parts of North Africa, where millions rely on the trade to make a living. New figures from the United Nations World Tourism Organisation (UNWTO) show that visits to North Africa fell by 8% this year, resisting a global upward trend. International tourism grew by 4.4% overall, to reach a total of 1.18 billion arrivals, according to the UNWTO.
    But countries such as Tunisia, Egypt and Morocco have been hit hard. Beach resorts such as Sharm el-Sheikh in Egypt, where a passenger jet was loaded with a bomb in November, and Sousse in Tunisia, where gunmen opened fire at holidaymakers in June, have seen visitor numbers sharply decline. Some 3, 500 British tourists left Tunisia in the days after the Sousse attack, in which 38 people—30 of them British—were shot by Islamist gunman at the Port El Kantaoul resort. Limited data available for Africa as a whole suggested that tourism was down by 3% to 53 million—8% in North Africa and 1% in Sub-Saharan Africa. But citing a "larger degree of uncertainty and unpredictability", the UNWTO has predicted between 3.5% and 4.5% of growth in global tourism in the next year.
