Speaking during a cabinet meeting in Seoul, Lee said the South Korean citizens had been detained without valid legal grounds and suggested the incident required a firm diplomatic response from his government.

Lee did not provide further details regarding the identities of the detained nationals or the circumstances surrounding the arrests.

The remarks marked one of the strongest public criticisms of Israel by the South Korean administration since escalating tensions in the Middle East triggered broader international scrutiny over maritime operations and regional security measures.

Lee also referred to international legal pressure facing Israeli Prime Minister Benjamin Netanyahu, saying many European countries appeared prepared to act on warrants issued by the International Criminal Court.
However, Lee said South Korea would make an independent assessment regarding any potential legal or diplomatic measures involving Israel.

The comments come amid heightened international debate over maritime interdictions, humanitarian flotillas and military operations linked to the conflict in Gaza and wider regional tensions involving Israel and its allies.

Neither Israeli officials nor South Korea’s foreign ministry immediately issued additional public statements regarding the detentions.
