Hezbollah vows to punish Israel 'for this sinful aggression'

Hezbollah vowed on Wednesday to punish Israel after hundreds of paging devices used by the militant group's members exploded in a deadly wave across Lebanon.

There was no immediate comment from Israel on the explosions that killed 12 people, including the 10-year-old daughter of a Hezbollah member, and wounded around 2,800 others.

Israel had announced hours earlier that it was broadening the aims of the war sparked by Hamas's October 7 attacks to include its fight against the Palestinian militant group's ally Hezbollah.

"We hold the Israeli enemy fully responsible for this criminal aggression," the group said in a statement on Tuesday, adding that Israel "will certainly receive its just punishment for this sinful aggression".

On Wednesday, the group vowed in another statement on Telegram it would continue its fight in support of Gaza while reiterating it would avenge Tuesday's attack.

"This path is ongoing and separate from the difficult reckoning that the criminal enemy must await for its massacre on Tuesday," it said.

Hezbollah leader Hassan Nasrallah will make a speech at 5pm (1400 GMT) on Thursday.

The wave of blasts killed 12 people, including two children, and wounded 2,800 others, 200 of them critically, Lebanese Health Minister Firass Abiad said Tuesday.

"This was more than lithium batteries being forced into override," said Charles Lister of the Middle East Institute.

"A small plastic explosive was almost certainly concealed alongside the battery, for remote detonation via a call or page."

Israel's spy agency "Mossad infiltrated the supply chain", he said.

The influx of so many casualties all at once overwhelmed hospitals in Hezbollah strongholds on Tuesday.

At one hospital in Beirut's southern suburbs, an AFP correspondent saw people being treated in a car park on thin mattresses, with medical gloves on the ground and ambulance stretchers covered in blood.

"In all my life I've never seen someone walking on the street...and then explode," said Musa, a resident of the southern suburbs, requesting to be identified only by his first name.

The 10-year-old daughter of a Hezbollah member was killed in east Lebanon's Bekaa Valley when his pager exploded, the family and a source close to the group said.

A son of Hezbollah lawmaker Ali Ammar was also among the dead, a source close to the group said.

Tehran's ambassador in Beirut was wounded but his injuries were not serious, Iranian state media reported.

Hezbollah backer Iran on Wednesday accused Israel of "mass murder", with foreign ministry spokesman Nasser Kanani condemning what he branded a "terrorist act" by Israel.

The attack dealt a heavy blow to the militant group, which already had concerns about the security of its communications after losing several key commanders to targeted air strikes in recent months.

A source close to Hezbollah said that "the pagers that exploded concern a shipment recently imported by Hezbollah of 1,000 devices" which appear to have been "sabotaged at source".

After The New York Times reported the pagers had been ordered from Taiwanese manufacturer Gold Apollo, the company said they had been produced by its Hungarian partner BAC Consulting KFT.

Lufthansa and Air France announced the suspension of flights to Tel Aviv, Tehran and Beirut until Thursday.
