A 26-year-old Romanian has been found dead in Nepal after going missing a week ago while trekking alone in the popular Annapurna region, a police officer said Monday.

The unnamed woman was apparently swept away by a swollen river she was trying to cross in the western district of Kaski at an altitude of nearly 2,000 metres (6,560 feet).

A search and rescue team found her body on a bank of the river late on Sunday, said district police officer Gajur Siddhi Bajracharya.

"We believe she was swept away by the river swollen because of monsoon rains," Bajracharya told AFP. Her body has been taken to the tourist town of Pokhara for a post mortem, he said.

Nepal's snow-capped peaks are a popular hiking destination, with around 150,000 trekkers visiting the Annapurna and Everest regions every year.

But the industry has suffered since a massive earthquake hit the Himalayan nation in April 2015, killing almost 9,000 people.

In October 2014 a major snowstorm ripped across the Annapurna circuit, killing 43 hikers, guides and porters during peak trekking season.
