Iran's parliament speaker and chief negotiator in talks with the United States, Mohammad Bagher Ghalibaf, said on Tuesday that the ball was in Washington's court to "prevent war".

"The countries of the region should know that, just as the Islamic Republic of Iran stands ready for battle with its finger on the trigger, it has also given the American side a powerful and rational response," he said in a televised speech. "The ball is now in America's court to prevent war."

The United States launched limited strikes on an Iranian island in the Strait of Hormuz on Tuesday, U.S. media reported, hours after President Donald Trump signaled diplomatic progress with Tehran.

The strikes, first reported by The Wall Street Journal, hit Qeshm Island, where Iranian state media reported five explosions in rapid succession.

U.S. President Donald Trump on Monday signaled progress in talks with Iran to avoid a return to war, as Tehran said "intensive" exchanges were underway while offering to reopen the Strait of Hormuz under strict conditions.

A deal with Tehran "could happen," Trump wrote on his Truth Social platform, a day before crucial U.S. midterm elections. He added that "Iran wants a settlement, as soon as possible."

Jordan's King Abdullah II on Monday said there would be no security in the Middle East region until the Palestinians' right to a homeland is fulfilled.

"We reiterate, time and again, that there can be no security or stability in our region without upholding the Palestinian people's right to their homeland," he said at the opening of Jordan's parliament.

The Middle East is braced for a possible return to all-out war. There are concerns that the United States, along with Israel, could strike Iran shortly after Tuesday's midterm elections in the U.S.

Two Iranian officials said their delegation had left Qatar after days of discussions but that messages with the U.S. continued to be exchanged through the mediator. The officials spoke on condition of anonymity due to the sensitivity of the talks.

U.S. President Donald Trump on Sunday reiterated his threat to resume strikes against Iran, telling a campaign rally that he may have to give Tehran "the hammer" at some unspecified time.

"And the only reason why I'm not finished with Iran is I want to be nice. I want to try and save all those lives if I can...But at some point we're going to have to give them the hammer," the 80-year-old president told supporters during a rally in Iowa ahead of the November 3 midterm elections.

The Israeli army has pulled back following an operation in the occupied West Bank city of Hebron, launched in the wake of an attack that killed two soldiers in late October, a military official said Monday.

"This morning, following the completion of all operational activities, the soldiers withdrew from the area of operation in Hebron. Counterterrorism activities throughout Judea and Samaria continue," the official said, using the biblical name for the Palestinian territory.

Yemen's Houthis said Monday that Saudi strikes targeted a key Red Sea port and oil facility in Hodeidah province, wounding seven people.

The Iran-backed group is fighting a Saudi-led coalition supporting Yemen's internationally recognised government after a civil war reignited in one of the world's poorest countries.

Iran's foreign ministry on Monday said it was considering a two-day plan to reopen the Strait of Hormuz if the U.S. agrees to its conditions, having previously proposed a one-week timeline.

"The possibility of implementing this plan in two days is another indication of Iran's good-faith approach. We have stated that, if Iran's demands are met, it would be possible to restore security to the Strait of Hormuz and resume the negotiating process within a short period," said foreign ministry spokesman Esmaeil Baqaei, adding that the "exchange of messages is still ongoing" via mediators.

The United Arab Emirates' presidential adviser said Sunday that his country hopes a diplomatic breakthrough in Qatar-led mediations is possible to avert a new round of confrontation between the U.S. and Iran.

The Iran war, which began on Feb. 28 with joint strikes by the U.S. and Israel followed by attacks by Iran on the Gulf nations, has made it "a watershed year" for the region and the world, UAE presidential adviser Anwar Gargash said at a security forum in Bahrain.
