Hundreds of pagers used by Hezbollah members exploded across Lebanon Tuesday, killing at least nine people and wounding some 2,800 in blasts the Iran-backed militant group blamed on Israel.
There was no immediate comment from the Israeli military on the wave of explosions, which came just hours after Israel announced it was broadening the aims of the war sparked by Hamas's October 7 attacks to include its fight against Hezbollah along its border with Lebanon.
The blasts "killed nine people, including a girl", Lebanese Health Minister Firass Abiad said.
He added that some "2,800 people were injured, about 200 of them critically" with injuries mostly reported to the face, hands and stomach.
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 told AFP, requesting anonymity to discuss sensitive matters.
Tehran's ambassador in Beirut was wounded in a pager explosion but his injuries were not serious, Iranian state media reported.
The influx of so many casualties all at once overwhelmed hospitals in Hezbollah strongholds.
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.
UN Special Coordinator for Lebanon Jeanine Hennis-Plasschaert denounced in a statement "an extremely concerning escalation", urging all sides to refrain from any action "which could trigger a wider conflagration that nobody can afford".
Hezbollah blamed Israel for the blasts and warned it would be punished.
"We hold the Israeli enemy fully responsible for this criminal aggression," the group said in a statement, adding that Israel "will certainly receive its just punishment for this sinful aggression".
The United States, Israel's top arms provider and close ally, was "not involved" and "not aware of this incident in advance", said State Department spokesman Matthew Miller.
The afternoon blasts hit Hezbollah strongholds across Lebanon and 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.
Analysts said Israeli intelligence services had somehow managed to infiltrate the supply chain used by Hezbollah for its pagers.
Israel's spy agency "Mossad infiltrated the supply chain", he said.
A source close to Hezbollah, asking not to be identified, told AFP that "the pagers that exploded concern a shipment recently imported by Hezbollah of 1,000 devices" which appear to have been "sabotaged at source".
Early Tuesday, Israel announced it was broadening the aims of the Gaza war to include its fight against Hezbollah along its border with Lebanon.
To date, Israel's objectives have been to crush Hamas and bring home the hostages seized by Palestinian militants during the October 7 attack that sparked the war.
"The political-security cabinet updated the goals of the war" to include "the safe return of the residents of the north to their homes", Israeli Prime Minister Benjamin Netanyahu's office said in a statement.
Since October, the unabating exchanges of fire between Israeli troops and Hamas ally Hezbollah in Lebanon have forced tens of thousands of people on both sides of the border to flee their homes.
Not formally declared as a war by Israel, the exchanges of fire have killed hundreds of mostly fighters in Lebanon, and dozens including soldiers on the Israeli side.
On Monday, Israeli Defence Minister Yoav Gallant warned that failing a political solution, "military action" would be "the only way left to ensure the return" of displaced residents to the border area.
"The possibility for an agreement is running out as Hezbollah continues to tie itself to Hamas," Gallant's office quoted him as telling visiting US envoy Amos Hochstein.
Netanyahu later told Hochstein he was seeking a "fundamental change" in the security situation on Israel's northern border.
Hezbollah deputy chief Naim Qassem said at the weekend that his group had "no intention of going to war", but that "there will be large losses on both sides" in the event of all-out conflict.
US Secretary of State Antony Blinken was due this week back in the region to try to revive stalled ceasefire talks for the Israel-Hamas war in Gaza.
After months of mediated negotiations failed to pin down a ceasefire, Washington has said it was still working with mediators Qatar and Egypt to finalise an agreement.
US officials have expressed increasing frustration with Israel as Netanyahu has publicly rejected US assessments that a deal is nearly complete and has insisted on an Israeli military presence on the Egypt-Gaza border.
The October 7 attack on southern Israel that sparked the war resulted in the deaths of 1,205 people, mostly civilians, according to an AFP tally based on official Israeli figures.
Militants also seized 251 hostages, 97 of whom are still held in Gaza, including 33 the Israeli military says are dead.
Israel's retaliatory military offensive has killed at least 41,252 people in Gaza, according to the Hamas-run territory's health ministry, which does not provide a breakdown of civilian and militant deaths.
General Assembly resolutions are not binding, but Israel has already denounced the new text as "disgraceful".
In Gaza, rescuers said several Israeli air strikes killed at least seven people overnight.
