Ankara,  Two Spanish tourists were killed and three others injured on Tuesday in a hot air balloon accident in Turkey's popular tourist destination of Cappadocia, local authorities said.

The balloon belonging to a private company took off from the Zelve Ruins of Avanos district in Nevsehir province and made a hard landing in the Killik region due to unexpected wind, Xinhua news agency quoted an official statement as saying.

A total of 28 passengers and two crew members were riding in the balloon.
