Iran Threatens ‘Painful Response’ After Israeli Airstrike on Beirut

Tensions in the Middle East escalated further on Sunday after a senior Iranian official threatened a “painful and decisive response” to Israeli airstrikes that targeted Beirut’s southern suburbs, a stronghold of Hezbollah.

The warning came hours after Israel launched attacks in the Lebanese capital, claiming the operation was a response to rocket fire directed at northern Israel. Lebanese reports said the strikes killed at least two people and injured eleven others.

Iran Issues Strong Warning

Ebrahim Rezaei, spokesperson for the Iranian parliament’s foreign policy and national security committee, condemned the attack and suggested retaliation could follow.

In a post on social media platform X, Rezaei said Iran would deliver a “decisive and painful response” to what he described as aggression by Israel.

He accused Israel of violating ceasefire agreements and argued that recent actions demonstrated a lack of commitment to diplomatic solutions.

The comments represent one of the strongest public warnings from Tehran since the latest round of tensions between Israel and Hezbollah began.

Israel Says Strike Targeted Hezbollah Facilities

Israeli officials said the operation was aimed at Hezbollah command centres located in Beirut’s Dahiyeh district.

Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz said the strike was carried out in response to attacks launched from Lebanon toward northern Israeli communities earlier in the day.

Israeli authorities maintain that the targets were linked to Hezbollah military operations rather than civilian infrastructure.

Several media reports also indicated that Israeli officials informed the United States about the planned operation before the strike took place.

First Strike Since Ceasefire Extension

The attack marked the first Israeli strike on Beirut since the ceasefire agreement was extended on 03/06/2026 following U.S.-mediated negotiations between Israel and Lebanon in Washington.

The ceasefire was intended to reduce cross-border hostilities, but its future now appears uncertain following the latest exchange of attacks and threats.

Hezbollah has previously rejected parts of the agreement, while Israel has repeatedly warned it would respond forcefully to any attacks originating from Lebanese territory.
