Beirut/IBNS: On Wednesday, hand-held radios used by Hezbollah detonated across southern Lebanon, marking the deadliest day in the country since cross-border hostilities began between Hezbollah and Israel nearly a year ago. 

This followed a similar explosion of the group's pagers the previous day, escalating tensions.

Lebanon’s health ministry reported that Wednesday's blasts claimed at least 20 lives and injured over 450 in Beirut’s suburbs and the Bekaa Valley.

The death toll from Tuesday’s explosions mounted to 12, including two children, with nearly 3,000 others wounded.

While Israeli officials have yet to comment, security sources pointed to Israel’s intelligence agency Mossad as the force behind the blasts, according to a Reuters report.

A Hezbollah official described the event as the group's most significant security breach to date.

The chaos unfolded against the backdrop of Israel’s ongoing war in Gaza, sparking fears of an escalation along the Lebanese border and a broader regional conflict.

Israeli Defense Minister Yoav Gallant signaled that a new phase of the war was beginning, requiring resilience.

Jordan's Foreign Minister Ayman Safadi accused Israel of driving the region toward war with multiple escalations.

The United States, denying involvement, said it was engaged in diplomatic efforts to prevent further conflict.

According to a US official, Israel informed Washington about a potential action in Lebanon but did not provide specific details.

One of Wednesday’s explosions occurred near a Hezbollah-organized funeral for victims of Tuesday’s blasts, where thousands of pagers exploded, injuring many Hezbollah members.

Hezbollah scrambled to deactivate other communication devices, tossing the components into metal containers.

Lebanon’s Red Cross said on X (formerly Twitter) that they had responded with 30 ambulance teams across the south and Bekaa Valley.

The radios involved in the blasts were identified as resembling ICOM's discontinued IC-V82 model, and the company has launched an investigation, according to Reuters.

The radios, along with the pagers that detonated the day before, were purchased by Hezbollah five months ago.

Reuters reported, citing sources, that Israeli operatives remotely triggered explosives they planted in 5,000 pagers before those devices entered Lebanon.

The United Nations (UN) Security Council is set to meet on Friday to discuss the blasts at the request of Arab states.

Iran’s envoy to Lebanon sustained injuries during Tuesday’s explosions, with conflicting reports on the severity. Iran has signaled it may take action in response to the attacks.

Meanwhile, in a retaliatory action, Hezbollah launched rocket strikes on Israeli artillery positions following the blasts, though no casualties were reported.

Despite growing tensions, Hezbollah appears to be trying to avoid full-scale war, though pressure for a stronger response is mounting, as per reports.

The ongoing cross-border skirmishes between Hezbollah and Israel, triggered by the Gaza conflict, have raised fears of a larger regional war involving the US and Iran.

Israel has redeployed troops to its northern border, preparing for potential conflict with Hezbollah.

In the midst of these tensions, mediation efforts by Egypt, Qatar, and the US to secure a Gaza ceasefire have struggled to make headway.

The White House stated it was too early to gauge the impact of the recent explosions on ceasefire talks.

Meanwhile, Hezbollah has vowed continued support for Hamas and hinted at further retaliation against Israel, reports Reuters.

As the situation escalates, Lebanon faces the grim prospect of deeper instability, compounded by existing economic and political crises.
