The State Department said Tuesday it is aware of approximately 70 Americans who remain unaccounted for in the Nepal-China border region following last month's catastrophic flooding, while 18 Americans have now made it to safety.
"We extend our deepest sympathy to all those affected by the flooding in Nepal, and their families, and we reaffirm our enduring friendship with the Nepali people," a State Department official told Fox News.
"The Department of State remains in close contact with the families of Americans who remain unaccounted for and is committed to providing regular updates as more information becomes available."

As search efforts continue, Nepalese authorities said rescuers are concentrating on three hydropower project tunnels where they believe dozens of workers may still be trapped beneath debris left by the Aug. 26 glacier collapse that triggered devastating flooding along the Nepal-China border, according to Reuters.
"Our search operation is focused on finding survivors, including in tunnels. Our bigger focus is on the Chilime hydroelectric project, where we believe people are trapped, because there was a canteen, residency and arrangements for food," Dharma Raj Upreti, chief of Nepal's disaster authority, told Reuters.
