Iran's Islamic Revolutionary Guard Corps launched ballistic missiles at northern Israel on Sunday, June 7, 2026, in retaliation for Israeli airstrikes in Lebanon [1, 2].

The escalation threatens to dismantle a fragile regional truce and risks expanding a conflict that had lasted approximately 100 days [3].

An Israeli military spokesperson said air defense systems were activated after missiles were detected headed toward Israel from Iran [4]. The Israeli military said the missiles targeted northern regions of the country [2]. There were no immediate reports of injuries or damage resulting from the barrage [5].

Tehran said the attack was a response to Israeli strikes on apartment buildings in the southern suburbs of Beirut, which Iran identified as Hezbollah command centers [1, 2]. A senior Iranian official said the missile launch was a "‘decisive and painful’ reply" [1].

An IRGC spokesperson said the barrage of missiles is a warning to Israel [4]. The Iranian government said the Israeli military crossed a red line by targeting the Beirut suburbs [2].

This event marks the first time Iran has launched a missile attack on Israel since a ceasefire was established on April 8, 2026 [5]. While the Guardian focused on the missiles targeting Israel, other reports indicated that Israeli aircraft also launched missiles at Beirut International Airport, damaging fuel stores, and runways [6].

“‘Decisive and painful’ reply”

The return to direct kinetic engagement between Iran and Israel signifies a collapse of the April 8 ceasefire. By targeting northern Israel in response to strikes on Hezbollah assets in Beirut, Iran is signaling that it views the security of its proxies in Lebanon as a direct extension of its own national security. This cycle of retaliation suggests that the 'red lines' established by both nations are now being actively tested, increasing the likelihood of a broader regional war.
