By Victoria Bryan BERLIN (Reuters) - Fearing for their safety in Tunisia after a gunman killed dozens of tourists, sun-seeking Europeans are switching to destinations such as Spain, Bulgaria or even Greece for holidays this year. Tunisia's tourism industry had been recovering after the Arab Spring unrest, and had become a popular lower-cost beach holiday spot for Europeans. Long-haul destinations are unlikely to pick up tourists originally destined for Tunisia, said travel analyst Angelo Rossini from market research firm Euromonitor.
