The Wall Street Journal reported that, after receiving threats attributed to the Islamic Republic, the U.S. Army has moved a number of its military aircraft out of the Mildenhall Air Force Base in the United Kingdom.

According to the report, several U.S. refueling aircraft were transferred on Monday to bases in Germany and other parts of Europe. The move comes a few weeks after the strategic U.S. bombers left RAF Fairford in the United Kingdom.

U.S. officials are assessing the nature and seriousness of these threats, and it is not yet clear whether there is an imminent threat of an attack.
