Several US military bases in Europe were put on heightened alert over the weekend due to concerns about a possible terrorist attack against US installations or personnel.

The US European Command headquarters in Stuttgart, Germany, raised its Force Protection Condition (FPCON) to “Charlie,” the second-highest alert level, indicating a likely threat of terrorist action.

Similar alerts were issued for other US military installations in Germany, including the US Army Garrison’s Rheinland-Pfalz and Ramstein Air Base, part of the Kaiserslautern Military Community.

The heightened security may cause severe delays at gate entrances, the Daily Express has reported.

A military spokesperson stated that the US European Command continuously assesses factors affecting the safety of the US military community abroad and takes additional measures as necessary.

However, specifics about the intelligence prompting the heightened security and the exact measures taken were not disclosed.
