The travel advisory comes after Washington has released a new travel advisory system, wherein a four-tiered ranking system enables Americans to understand the safety risks associated with travelling abroad.
As per the new ranking system of the State Department, the Americans have been asked to exercise normal precautions while visiting the first tier nations like Canada and Sweden, while fourth level states such as Iran and North Korea are designated as "Do not travel."
Further, the advisory stated that the people traveling the prohibited places would not be provided any emergency assistance, as the "U.S. government employees are prohibited from traveling there".
Meanwhile, the spokesperson for Russia's Foreign Ministry, Maria Zakharova, decried the warning as a scare tactic meant to further the rift between former Cold War foes.
