This follows a number of attacks by other Iranian-backed proxies based in Iraq.
Israel and Hezbollah are exchanging hundreds of cross-border strikes in the wake of the shocking explosions of wireless devices across Lebanon last week.
Hezbollah senior commander Ali Karaki, who was targeted in Monday’s strike on Beirut, survived the attack, Hezbollah officials said.
Two senior Israeli sources confirmed to ABC News that Karaki had been the target of the strike.
At least six people were injured Monday in an Israeli strike on southern Beirut, according to Lebanese state media.
The Israel Defense Forces conducted the targeted missile strike on a residential building in Bir al-Abd, a southern suburb of Beirut.
The U.S. is sending "a small number" of additional troops to the Middle East amid growing tensions in the region, Pentagon press secretary Maj. Gen. Pat Ryder announced Monday.
"In light of increased tension in the Middle East, and out of an abundance of caution, we are sending a small number of additional U.S. military personnel forward to augment our forces that are already in the region," Ryder said.
He would not give additional details on the size or nature of these additional forces, citing operational security concerns.
As Israeli forces continue to bombard southern Lebanon, the Israel Defense Forces is calling on civilians living in Lebanon’s Beqaa Valley to leave now. This comes after an earlier call for civilians to leave southern Lebanon.
"I urge the Lebanese residents of the villages in the Beqaa Valley who are inside or near houses where rockets and weapons are stored, to move away immediately! For your safety and protection," IDF spokesman spokesperson Rear Adm. Daniel Hagari said Monday.
Hagari claimed every house the IDF is striking contains rockets, missiles and unmanned aerial vehicles "that are intended to kill Israeli civilians."
