More than 1,200 people, including Hezbollah fighters and medics, were wounded on Tuesday when the pagers they use to communicate exploded across Lebanon.

According to international media reports, the pagers exploded in the southern suburbs of the capital, Beirut, known as Dahiyeh on Tuesday, security sources said, adding that communication devices were also exploded in the south of Lebanon.

Officials said the blasts appeared to be a remote cyber attack by the Israeli regime at a time of rising tensions across the Lebanese border.

Footage shared on social media showed the wounded were attended by passers-by. Groups of people also gathered at the entrance of buildings to check on people they knew who may have been injured.

In a statement, Hezbollah said at least three people, including a girl, were killed in the pager explosions and many others sustained injuries in the blasts.

Hezbollah said that relevant authorities are currently conducting security and scientific investigations to determine the causes of these simultaneous explosions.

The group emphasized that its resistance forces remain at the highest level of readiness to defend Lebanon and its people.

People said blasts were taking place half an hour after the initial explosions and ambulances could be heard non-stop.

Over 50 ambulances from the Red Cross were sent to the scene to help transport casualties to hospitals.

The Lebanese Ministry of Health has asked for all medical workers to remain on alert and respond to the incident if needed.

Lebanon’s Minister of Health, Firas Abiad, said the number of injured was in the “hundreds” and there were some fatalities from the explosions.

Iran’s ambassador to Lebanon, Mojtaba Amani, was also one of the injured in the explosions.

The Iranian Embassy in Beirut later announced that Ambassador Amani sustained minor injuries, but he was in good condition.

There was no immediate comment from the Israeli military, which has been exchanging fire with Hezbollah since early October, shortly after the occupying regime launched its war on Gaza after the Palestinian Hamas resistance group carried out Operation Al-Aqsa Storm against the usurping entity in retaliation for its intensified atrocities against the Palestinian people.
