A Reuters journalist was killed on Friday and six others from AFP, Reuters and Al Jazeera were wounded while working in southern Lebanon, the three news organisations said.
A group of journalists from different media outlets was near the village of Alma al-Shaab, close to the border with Israel, when they were caught up in cross-border shelling, one of the two wounded AFP correspondents said.
A Lebanese security source had told AFP that initial Israeli shelling followed an infiltration attempt by a Palestinian faction from the Lebanese side of the border.
"We are deeply saddened to learn that our videographer, Issam Abdallah, has been killed," Reuters said in a statement, adding he "was part of a Reuters crew in southern Lebanon".
AFP photographer Christina Assi and AFP video journalist Dylan Collins were working in the area. Both were taken to a hospital in Tyre for treatment.
Two other Reuters reporters, "Thaer Al-Sudani and Maher Nazeh also sustained injuries and are seeking medical care," Reuters said, adding it was "urgently seeking more information".
Al Jazeera said two of their reporters were among the wounded, blaming "Israeli bombing on their vehicle". They named them as Carmen Joukhadar and Elie Brakhya.
"We are deeply concerned that a group of journalists who were clearly identified have been killed and injured while doing their job," said AFP`s global news director Phil Chetwynd.
"We send our deepest condolences to our friends at Reuters for the loss of Issam and we are all pulling for our injured colleagues in hospital."
`Must be halted`
AFP correspondents had reported shelling targeting the villages of Dhayra, Alma al-Shaab and Adaysseh, with smoke billowing from the area.
The Israeli army had said in a statement not long before the journalists were hit: "A short while ago, a blast occurred on the border fence in Hanita (Western Galilee)," referring to a point in Israel just across the border from Alma al-Shaab.
"Light damage was caused to the wall. In response, IDF (army) forces are currently responding with artillery fire towards Lebanese territory."
Iran-backed Shiite Muslim group Hezbollah said it retaliated by firing at several positions in Israel.
An Israeli spokesperson said later on X, formerly Twitter, that a remote-operated army aircraft was striking Hezbollah targets.
The army also said that an "unidentified target crossed into Israeli territory from Lebanese territory and was successfully intercepted by air defence fighters".
The United Nations Interim Force in Lebanon, UNIFIL, said it had "actively engaged with authorities on both sides of the Blue Line to de-escalate the situation".
The UN demarcation line was drawn when Israeli troops withdrew from south Lebanon in 2000 after a 22-year-long occupation of the area.
Lebanon and Israel are still technically at war, and UN peacekeepers have been deployed in Lebanon since 1978.
"The potential for this escalation to spiral out of control is clear, and it must be halted," the force warned in a statement.
`Directly targeted`
In 2006, Israel and Hezbollah fought a conflict which left more than 1,200 dead in Lebanon, mostly civilians, and 160 in Israel, mostly soldiers.
Lebanese Prime Minister Najib Mikati said Israeli forces had "directly targeted journalists as part of their ongoing attacks on Lebanese territory".
UN chief Antonio Guterres expressed his "deepest condolences" to the family of Reuters journalist Abdallah and other journalists killed in the line of duty.
"I want to say how much this demonstrates the enormous risk of spillover of this conflict, namely in relation to Lebanon," Guterres said of the Israel-Hamas conflict.
White House spokeswoman Karine Jean-Pierre said on X: "Our hearts are with the families of the journalists who lost their lives and those who suffered injuries in Lebanon. Journalists do critical work to better inform the public, often in dangerous conditions."
The Israel-Lebanon border has seen a series of flare-ups since a bloody attack by the Palestinian group Hamas on Israel on October 7.
Hundreds of Hamas gunmen stormed across the border from Gaza into Israel on Saturday, killing more than 1,300 people, most of them civilians, and seizing about 150 hostages.
Israel has retaliated by bombarding Hamas targets in the Gaza Strip, killing some 1,900 people, and warned 1.1 million people in northern Gaza to evacuate to the south.
