Tourism arrivals were up by 5.0 per cent in Europe, Asia-Pacific and the Americas but fell by 8.0 per cent in North Africa where nations like Tunisia were hit by terrorist attacks, it said in a statement.
The Madrid-based body had earlier predicted international tourism arrivals would increase by 3.0-4.0 percent in 2015, after expanding by 4.7 percent in the previous year.
Global tourism figures were hard hit by the global financial crisis, declining 4.0 percent in 2009 as an outbreak of swine flu also contributed to cash-strapped people staying at home but have risen in each year since.
This attack and others came as North African countries still struggle to regain the trust of holidaymakers scared off by the Arab Spring uprisings that swept the region in 2011.
