TEHRAN -- Iran's Parliament Speaker Mohammad Bagher Ghalibaf said on Wednesday certain data demonstrate that the "enemies" are preparing for an operation to occupy an Iranian island with the support of a regional state.

"If they take any step forward, all of the vital infrastructure of that regional country will come under (Iran's) unrelenting attacks without any restriction," Ghalibaf made the remarks in a post on social media platform X.

In a separate post earlier in the day, Ghalibaf said Iran is closely monitoring all US movements in the region, especially its troop deployments.

"What the generals have broken, the soldiers can't fix; instead, they will fall victim to (Israeli Prime Minister Benjamin) Netanyahu's delusions," he said, warning, "Do not test our resolve to defend our land."

Ghalibaf's remarks came amid reports that Pentagon is expected to send thousands of soldiers from the US Army's elite 82nd Airborne Division to the Middle East.

On Feb 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Iran's Supreme Leader Ali Khamenei, along with senior military commanders and civilians. Iran responded by launching waves of missile and drone strikes targeting Israel and US bases and assets in the Middle East.
