Iran has warned that the ongoing conflict in the Middle East could spread even further if the United States resumes military strikes against the Islamic Republic.

The warning came on Sunday as Israeli Prime Minister, Benjamin Netanyahu, prepared to travel to Washington for a meeting with U.S. President, Donald Trump.

Iranian Army spokesman, Mohammad Akraminia, said Tehran was prepared for any possible development, insisting that the country would respond to any renewed American military action.

“I believe that if the Americans once again fall for the Zionists’ deception, or move in line with them, and insist on continuing the war, particularly through air strikes, geographically this will expand further,” Akraminia told state television.

Iran Says Conflict Has Reached Red Sea and Gulf Region

He said the conflict had already extended to the Bab al-Mandab Strait at the entrance to the Red Sea, following a recent military escalation involving Yemen’s Iran-backed Houthi rebels and Saudi Arabia.

“The scope of our operations now encompasses the entire region, from U.S. bases in Jordan to the countries along the Persian Gulf,” he said.

According to the army spokesman, the situation facing the United States in the Middle East was “difficult and unsettled,” adding that Washington appeared to be searching for “a new strategy.”

“We are prepared for each of the options and scenarios that appear likely,” he added.

Netanyahu To Meet Trump Amid Growing Tensions

On Friday, Israel announced that Netanyahu would meet Trump at the White House on Tuesday.

The two leaders have met six times since Trump returned to office last year, with their most recent meeting taking place in Washington on February 11.

However, the upcoming visit comes amid growing differences between the two leaders over the handling of the war with Iran.

“As part of the visit, the Prime Minister will meet with President Trump at the White House on Tuesday and attend the funeral service for Senator Lindsey Graham, a friend of Israel,” Netanyahu’s office said, adding that the Israeli leader would leave for Washington on Monday.

Trump and Netanyahu had been closely aligned after Trump returned to the White House, launching a joint war against Iran in late February, which both sides initially described as a success.

Netanyahu has repeatedly referred to Trump as “the greatest friend” Israel has ever had in the White House.

However, tensions have emerged in recent months, particularly over whether military pressure on Iran should continue or whether the conflict should be resolved through diplomacy.

“We get along very good. (Netanyahu) knows who the boss is,” Trump said earlier this month in a phone interview with Axios.

Relations between the two leaders reportedly reached a low point in April during negotiations over an initial U.S.-Iran ceasefire, which has since collapsed, with Trump launching angry, profanity-laced attacks against his Israeli ally.
