Iran has warned it may withdraw from maintaining regional maritime security, including in the Strait of Hormuz, if European nations reinstate international sanctions through the UN. A senior Iranian lawmaker made the remarks ahead of E3-Iran talks in Istanbul. The EU trio—UK, France, and Germany—has threatened to activate the snapback mechanism if Iran fails to engage in meaningful nuclear negotiations. Tehran argues the E3 no longer has legal standing to trigger the process due to their stance on recent Israeli and U.S. attacks.
