In a recent travel advisory, the Foreign Office expressed concern over the potential for an unforeseen escalation in the ongoing tensions between the two countries.

Additionally, Germans in Iran may face the risk of arbitrary arrests and lengthy imprisonment.

The Foreign Office's statement read, "In the current tensions, especially between Israel and Iran, there is a risk of a sudden escalation." This warning comes as a response to the increasing tensions between the two nations, which have been simmering for some time.

The Foreign Office further cautioned that transportation routes, including air, land, and sea, could be disrupted due to the escalating situation.

The advisory specifically targeted German citizens in Iran, stating that they are at a heightened risk of being arbitrarily arrested and interrogated, potentially leading to lengthy prison sentences.

Dual citizens holding both Iranian and German nationalities are considered to be at an even greater risk.

The Foreign Office's warning follows similar advisories issued by other Western countries, including the United States and the United Kingdom, urging their citizens to leave Iran due to the heightened tensions and the potential for unforeseen events.

The situation remains fluid, and it is unclear when it will de-escalate or what the long-term implications will be for Iran and the region as a whole.

In summary, Germany's Foreign Office has advised its citizens to leave Iran due to the heightened tensions between Iran and Israel, which pose a risk of sudden escalation and arbitrary arrests for Germans in the country.

The advisory comes as part of a larger trend of Western countries urging their citizens to depart from Iran amidst the ongoing tensions.
