At least one Israeli strike early on Friday hit outside the perimeter of Beirut's international airport, Reuters news agency reported, citing a source in the Lebanese Ministry of Transport and Public Works.
Earlier in the evening, a source close to Hezbollah told AFP an Israeli strike had targeted a warehouse next to Beirut airport, in the capital's south.
The extent of the damage was not immediately clear.
Israel also launched renewed strikes on Beirut's southern suburb of Dahiyeh, a stronghold of the Iran-backed armed group Hezbollah, near midnight on Thursday.
The air raids targeted Hezbollah official Hashem Safieddine, rumored successor to assassinated Hezbollah leader Hassan Nasrallah, report Axios and the New York Times.
Safieddine's fate was not clear, he said.
Israel's military has not yet commented on whether it targeted Safieddine.
WHO says 28 health workers killed in Lebanon in the past day
The World Health Organization (WHO) said 28 health workers in Lebanon were killed in the past day, and it called for a cease-fire.
The UN health agency said access to medical care is becoming limited as three dozen health facilities closed in the south and five hospitals were either partly or fully evacuated in Beirut.
WHO chief Tedros Adhanom Ghebreyesus described the dire situation, noting that health workers are not showing up at their jobs because they've fled areas that have been bombed.
He said WHO had to scrap plans to fly in medical and trauma supplies Friday because Beirut international airport is mostly closed.
Lebanon's health minister, meanwhile, said Israeli strikes that hit hospitals and health care centers violate international law.
The Lebanese Red Cross also said an Israeli strike wounded four of its paramedics and killed a Lebanese army soldier as they were evacuating wounded people from the south.
It said the convoy near the village of Taybeh, which was accompanied by Lebanese troops, was targeted Thursday despite coordinating its movements with UN peacekeepers.
There was no immediate comment from the Israeli military.
Israel orders new Lebanon evacuations
Israel's military has ordered residents of more than 20 towns in southern Lebanon to evacuate their homes as it continued with a cross-border incursion.
The latest warnings took the number of southern towns subject to evacuation calls to 70.
Among the towns affected is the provincial capital Nabatieh as well as other communities north of the Litani River, which formed the northern edge of the border zone established by the UN Security Council after Israel and Hezbollah fought a war in 2006.
The announcement suggests the Israeli military may widen a ground operation launched earlier this week against the militant group.
UN Security Council backs Guterres after Israel bars him from country
The UN Security Council has affirmed its full support for Secretary-General Antonio Guterres after Israel banned him from entering the country.
The 15-member body said in a statement that "any decision not to engage with the UN Secretary-General or the United Nations is counterproductive, especially in the context of escalating tensions in the Middle East."
The statement did not name Israel.
The UN's most powerful body also "underscored the need for all member states to have a productive and effective relationship with the secretary-general and to refrain from any actions that undermine his work and that of his office."
The UN statement comes after Israel's Foreign Minister Israel Katz announced Wednesday that Guterres is "persona non grata" — not welcome — in the country.
The Israeli government has accused the UN chief of being biased against Israel.
US 'discussing' possible Israeli strikes on Iran oil sites
US President Joe Biden has said that Washington is discussing possible Israeli strikes on Iran’s oil facilities as retaliation for Tehran’s missile attack on Israel. "We're discussing that," Biden told reporters.
His comments contributed to a surge in global oil prices amid rising fears of potential supply disruptions. Brent, the international benchmark, surged over 5% to $77.62 (€70.3) a barrel, with US contract West Texas Intermediate rising similarly.
Biden, however, added that he thought an all-out war could be avoided.
"I think we can avoid it, but there's a lot to do yet," he told reporters, stressing that "we're going to help Israel."
After Tuesday's missile attack, Israeli Prime Minister Benjamin Netanyahu vowed retaliation.
The US said it would work with its longtime ally to ensure Iran faced "severe consequences."
Iranian President Masoud Pezeshkian, meanwhile, said that Tehran would be ready to respond.
"Any type of military attack, terrorist act or crossing our red lines will be met with a decisive response by our armed forces," he said.
