Seoul confirms US cancels joint marine drills amid Iran tensions

South Korea's defence ministry confirmed on Monday that planned joint marine exercises with the United States have been cancelled, citing security concerns related to the escalating situation in Iran.

The decision represents the second postponement of scheduled joint drills between the two allies in a matter of weeks. Last week, the Trump administration ordered a reduction in the scope of an annual joint military exercise, signalling a shift in the approach to combined operations on the Korean peninsula.

While specific details regarding the scale and timing of the cancelled marine drills remain limited, the move underscores broader uncertainties in US military planning amid heightened tensions in the Middle East. Seoul's defence ministry stated it is coordinating with Washington on alternative scheduling and operational plans.

The cancellations come as South Korea faces pressure to balance its alliance commitments with the United States against regional security challenges and diplomatic considerations. Military officials from both nations are expected to discuss the implications of the postponements in coming days.
