US President Donald Trump was compelled to switch aircraft during his departure from the NATO summit after the Secret Service identified a credible threat linked to Iran-aligned groups, according to reports from Der Spiegel.
The security detail intervened to move the president to a different plane, citing intelligence regarding a planned attack on the new Air Force One.
The incident highlights the ongoing security challenges facing the US administration as geopolitical tensions with Iran remain high.
The threat assessment prompted an immediate operational response, ensuring the president's safety but drawing attention to the vulnerabilities of high-profile diplomatic travel.
This development follows recent scrutiny over security protocols for presidential travel.
The US Department of Justice recently moved to withdraw subpoenas issued to New York Times journalists who had reported on security concerns regarding the use of a Qatari-donated Air Force One.
