Iran's leaders are warning of a broader military response if the United States and Israel launch new attacks, as tensions rise ahead of Tuesday's U.S. midterm elections and diplomatic efforts to prevent another round of fighting remain uncertain.

Iran's new Supreme Leader, Ayatollah Mojtaba Khamenei, met with senior military commanders and directed that any response to threats from the United States or Israel be immediate and without “geographic limits.” He also called for an expansion of Iran's list of potential targets.

Iranian security chief Mohsen Rezaei issued a separate warning on X, saying that any attack would bring “devastating blows on the aggressor using new weapons.”

The warnings come as U.S. officials have reportedly urged regional allies to prepare for possible renewed American military action against Iran after the November 3 elections. President Donald Trump has not made a final decision, but has repeatedly indicated that further strikes remain an option.

According to two diplomats briefed on the discussions, U.S. officials have warned that a new military campaign could last several days. Regional governments are also concerned that Iran and its allied groups could retaliate against energy facilities and other critical infrastructure, potentially prolonging the conflict.

Despite the threats, diplomatic efforts are continuing. An Iranian delegation recently left Qatar after several days of discussions, but messages between Tehran and Washington are still being exchanged through Qatari mediators.

Iranian Foreign Minister Abbas Araghchi said Tehran continues to give diplomacy a chance. Iran is seeking an agreement that would include reopening the Strait of Hormuz, provided Washington meets its conditions, including lifting restrictions on Iranian ports.

The situation remains tense, with both sides maintaining military options while negotiations continue. Regional officials have warned that another escalation could have serious consequences across the Middle East.
