From SA to Australia: Where the tourists missing in Nepal are from

Tourists from South Africa, India, Australia, China and other countries are among those missing after deadly Nepal-Tibet floods.

More than 1,300 people were reported missing and at least 165 were confirmed dead after flash floods and landslides at the Nepal-Tibet border.

Nepal's disaster agency said 823 people were unaccounted for on Thursday, a figure that included at least 579 Nepali and foreign tourists.

The disaster agency's figure did not list the nationalities of the uncontacted foreigners .

Across the border, China said 558 people -- almost half of which are foreigners -- were missing.

Hikers and climbers from around the world flock to the Himalayan nation to test themselves on some of the world's highest peaks, Mount Everest among them.

It is not uncommon for the number of missing people to increase, but also decrease in the wake of a major disaster.

Double-counting of dual nationals, matching bodies with people listed as missing and the chaos of a calamity can all contribute to fluctuations in the figures.

In China, authorities said Thursday that 298 Chinese people were missing in the wake of the disaster.

According to the Nepal Tourism Board list that has not been updated since Wednesday, 142 nationals from neighbouring India were missing.

They were in the country with three travel agencies: Samrat Tours & Travels, Leaf Holiday and Himalayan Glacier.

Nepal's latest figure of unaccounted for tourists lumped together foreigners and Nepalis, and did not breakdown the foreigners' nationalities.

Ukraine's foreign ministry said Nepal's Tourist Police had informed them that they believed 53 Ukrainian nationals were missing.

They included a group of 46 Ukrainian tourists with whom the authorities in Nepal had lost contact, the ministry added.
