For various reasons, tourist seasons after 2005 have been disappointing for Alanya's tourism industry. Among the reasons blamed were increased PKK violence, the H5N1 bird flu found in Van, and the Mohammad cartoon controversy. Alanya officials have responded with a variety of publicity initiatives, including baking the world's longest cake on April 26, 2006, a Guinness World Record. The economy has also suffered due to investment in more than properties. Israeli tourists, commonly arriving via cruise ship, have also declined sharply by about 85% from 2009 to 2011 due in part to strained relations between Turkey and Israel.
