Germany urges citizens to leave Iran

Germany warned its citizens to leave Iran, saying that there was a risk of a sudden escalation following Tehran's vow to respond to Israel after an air strike attack on its consulate compound in Syria.

Germany further warned its citizens that they might be at risk of being arrested in Iran.

"In the current tensions, especially between Israel and Iran, there is a risk of a sudden escalation," the foreign office wrote in a new travel warning.

"German citizens are at concrete risk of being arbitrarily arrested and interrogated and being given long prison sentences. Dual citizens with Iranian and German nationality are especially at risk."
