DUBAI/JERUSALEM – Tehran on Jan 11 threatened to retaliate against Israel and US bases in the event of US strikes on Iran, delivering the warning to Washington as Israeli sources said Israel was on high alert for the possibility of any US intervention.

With Iran’s clerical establishment facing the

biggest anti-government protests since 2022

, US President Donald Trump has repeatedly threatened to intervene in recent days, warning Iranian leaders against using force against demonstrators.

On Jan 11, Mr Trump said the US stands “ready to help”.

Iranian Parliament Speaker Mohammad Baqer Qalibaf, speaking in Parliament on Jan 11, warned the United States against “a miscalculation”.

“Let us be clear: In the case of an attack on Iran, the occupied territories (Israel) as well as all US bases and ships will be our legitimate target,” said Mr Qalibaf, a former commander in Iran’s Revolutionary Guards.

Three Israeli sources, who were present for Israeli security consultations over the weekend, said Israel was on a high alert footing, but did not elaborate on what that meant.

An Israeli government spokesperson declined to comment. The Israeli military did not immediately respond to a request for comment.

Israel and Iran fought a

12-day war in June

, in which the US joined Israel in launching air strikes. Iran retaliated for those US strikes by firing missiles at an American air base in Qatar.

Protests have spread across Iran since Dec 28, 2025,
