Iran's Islamic Revolutionary Guard Corps (IRGC) launched ballistic missiles at the Ramat David Air Base in northern Israel on Sunday, 8 June, in what it described as a direct response to Israel's 'widespread crimes' in southern Lebanon, including the killing and displacement of civilians. The strike marks a sharp escalation in the ongoing conflict, coming weeks after a ceasefire between Iran, the United States, and Israel took effect on 8 April.

Iran's Warning to Israel

Ali Abdollahi, chief commander of Iran's Khatam al-Anbiya Central Headquarters, warned that Israel will face more 'crushing and regret-inducing blows' if it expands its attacks on southern Lebanon and the Dahieh district south of Beirut, or retaliates against Iran's actions. In a statement aired by Iran's semi-official Fars news agency, Abdollahi said 'devastating' attacks would begin against Israel and its supporters unless the assaults on Lebanon ceased immediately.

Abdollahi accused Israel of escalating its 'malicious actions' against Lebanese civilians daily, allegedly with a US 'greenlight' and amid the silence of international organisations. He further alleged that Israel has been 'perpetrating war crimes by using banned weapons, including phosphorus bombs.'

The IRGC Strike and Its Justification

In a statement published on its official outlet Sepah News, the IRGC said the Ramat David Air Base had been the origin of 'aggressions' against Lebanon, making it a primary target. The Corps emphasised that Iran's acceptance of the 8 April ceasefire was conditional on a truce across all fronts. According to the IRGC, the United States and Israel failed to honour those commitments, continuing what it described as 'aggressions and crimes' in Lebanon and allegedly attacking 'Iranian shores and vessels in the Strait of Hormuz, the Sea of Oman, and the Indian Ocean.'

The IRGC characterised Sunday's military operation as a warning shot, adding that any repetition of 'aggressions' would trigger broader responses encompassing 'all US and Israeli targets in the West Asia region.'

Senior Official's Statement on X

Mohsen Rezaei, military adviser to Iran's Supreme Leader Mojtaba Khamenei, posted on social platform X on Sunday, stating: 'Iran had repeatedly declared that it would not tolerate violations of the ceasefire or aggression against Lebanon.' He added, 'This response is a warning for them to cease their villainy; every new action will be met with a more crushing response and heavier costs.'

Airspace Closure and Regional Impact

Following the missile strikes, Iran's Civil Aviation Authority announced the closure of the country's western airspace until further notice, citing security and safety assessments, according to the semi-official Tasnim news agency. The closure signals the operational scale of Iran's military posture and carries significant implications for regional air traffic.

Ceasefire Background and Diplomatic Track

The 8 April ceasefire ended 40 days of hostilities that began after Israel and the United States launched joint attacks on Tehran on 28 February. In recent weeks, Iran and the United States have reportedly exchanged several proposals outlining conditions for a lasting peace and are working to finalise a memorandum of understanding aimed at formally ending the conflict. Sunday's escalation raises serious questions about whether that diplomatic track can survive fresh military action on both sides.
