The strike near the Cola Bridge, a major intersection in the city, is the first time a location within the Lebanese capital’s city limits has been hit in the current war, reported CNN.

PFLP said those killed in the attack were identified as Mohammed Abed Al-Al, a member of its political bureau and head of the military-security department, Imad Odeh, a member of its military department and military command in Lebanon, and Abdul Rahman Abed Al-Al.

The Israeli military on Sunday said another top leader of the Iran-backed armed outfit Hezbollah group has been eliminated.

IDF said it had eliminated Hezbollah's Preventative Security Unit Commander Nabil Qaouk.

He was eliminated during an airstrike in Beirut.

IDF posted on X: "ELIMINATED: The Commander of Hezbollah's Preventative Security Unit and a member of their Executive Council, Nabil Qaouk, was eliminated in a precise IDF strike."

"Qaouk was close to Hezbollah's senior commanders and was directly engaged in terrorist attacks against the State of Israel and its citizens. He joined Hezbollah in the 1980s and was regarded as an important source of expertise in his field, having served as the Deputy Commander of the southern region on the Operational Council, Commander of the southern region and Deputy Commander of the Operational Council," it said.

The IDF said it will continue to strike and eliminate the commanders within the Hezbollah terrorist organization and will act against anyone who threatens the citizens of the State of Israel.

Israel, earlier confirmed Hassan Nasrallah, the chief of Iran-backed Hezbollah militia group, was killed during an airstrike in Beirut.

The conflict between IDF and Hezbollah has intensified in recent times.

According to media reports, the Israeli airstrikes on the terror group this week left over 700 people dead in Lebanon.
