Reuters journalist Issam Abdallah killed in southern Lebanon, 6 others wounded

At least one journalist was killed and six others injured on Friday in southern Lebanon when Israel fired artillery into the area they were gathered.

The incident - which impacted journalists from Reuters, the Agence France-Presse wire service and Al Jazeera - marks one of the worst press catastrophes yet to emerge from Israel's war against Hamas.

The Israel Defense Forces acknowledged firing artillery into Lebanon, telling CNN that it was in response to an explosion near the security fence near a kibbutz. Additionally, a Lebanese security source told CNN that an Israeli Apache helicopter was seen over the site of the attack.

The IDF, however, did not respond to additional questions from CNN related specifically to the journalists being hit. The journalists were wearing press-labeled jackets at the time of the attack.

Reuters said in a statement that it was "deeply saddened" to learn that one of its videographers, Issam Abdallah, had been killed in the incident.

"We are urgently seeking more information, working with authorities in the region, and supporting Issam's family and colleagues," Reuters said.

The news agency said two other Reuters journalists, Thaer Al-Sudani and Maher Nazeh, were also injured in the incident.
