The US State Department warns not to travel to Yemen, because of terrorism, civil unrest, health risks, kidnapping, and armed conflict. The US embassy ceased operations in the country in 2015.
"No part of Yemen is immune to violence," the advisory warns. Military conflict has caused significant destruction of infrastructure, housing, schools, medical facilities, and utilities, limiting supplies of water, electricity and medicine. On top of this, terrorism attacks continue and there is a threat of kidnapping by terrorists, criminals, or non-government actors.
Yemen also has the world's largest cholera outbreak, which is throughout the entire country.
If people do travel to Yemen, they're advised to prepare the appropriate paperwork before leaving, as well as establishing a security plan or consulting with professional security firms.
