Beirut, Lebanon – Iran has warned the United States that a comprehensive Israeli assault on Ali al-Tahir Hill in southern Lebanon would trigger a direct and large-scale Iranian response due to the presence of Islamic Revolutionary Guard Corps (IRGC) personnel alongside Hezbollah fighters, according to a Reuters report citing informed sources.
Omani Mediation and Subterranean Positions
The Iranian warning was conveyed to Washington via Oman acting as a diplomatic intermediary. Tehran emphasized that any military operation aimed at capturing the strategic hill—which houses an underground command hub and ammunition depots—would provoke a major Iranian counterattack. Regional sources report that over a dozen IRGC personnel, including senior officers, are present within the subterranean compound.
Meanwhile, military assessments remain divided regarding the operational status of forces inside the position. While Israeli air strikes have targeted tunnel entrances, the White House denied reports claiming it pressured Israel to refrain from assaulting the site.
Escalation Risks and Full-Scale War Threats
Ultimately, Hezbollah warned that an Israeli storming of Ali al-Tahir Hill would signal an immediate return to all-out war, threatening heavy rocket barrages against population centers in northern Israel. Security sources indicate an Israeli ground attempt to secure the hill remains possible in the coming weeks as regional tensions escalate.
