Israeli warplanes targeted what the IDF said were Hezbollah targets.
The Israel Defense Forces continued its intense airstrike and ground campaigns in Gaza -- particularly in the north of the strip -- and in Lebanon, with Israeli attacks on targets nationwide including in the capital Beirut. The strikes form the backdrop for a fresh diplomatic push by the White House ahead of President-elect Donald Trump's return to the Oval Office in January.
Tensions also remain high between Israel and Iran after the former launched what it called "precise strikes on military targets" in several locations in Iran following Tehran's Oct. 1 missile barrage.
The Israel Defense Forces said it attacked transit routes used by Hezbollah to transfer weapons from Syria to Lebanon on Wednesday.
The strikes on these routes targeted the capabilities of Hezbollah's 4400 unit, which is responsible for transferring weapons from Iran to Lebanon, according to the IDF.

A collection of 30 aid organizations warned in a statement on Thursday that Israel's offensive in north Gaza has suppressed the level of humanitarian aid entering the strip to "its lowest level in over a year."
"The ongoing Israeli bombardment, siege, and evacuation orders are severely hampering aid distribution," the agencies -- which included Mercy Corps, Oxfam, Save the Children and the Norwegian Refugee Council -- said.
"Israeli airstrikes killed at least 20 aid workers between Oct. 10 and Nov. 13," the statement added. "These staff were killed in displacement camps, at home and while delivering life-saving assistance."
"Israeli forces killed aid workers both in areas under evacuation, such as Jabalia and Beit Lahiya, and in the government of Israel-designated 'humanitarian zone,' underscoring that nowhere is safe for Palestinians," the NGOs added.
The Israel Defense Forces said Thursday it hit more than 100 targets in Gaza and Lebanon in the previous 24 hours.
The IDF said the targets included weapons storage facilities, launchers aimed toward Israeli territory, command centers and other enemy military sites.
The strikes included the killing of a militant cell that fired anti-tank missiles at Israeli troops in northern Gaza, the IDF said.

The families of American hostages being held by Hamas met with President Joe Biden for roughly an hour and a half Wednesday afternoon, according to the White House.
They discussed where the situation now stands and noted that the topic was also, apparently, on the agenda for Biden and President-elect Donald Trump’s sit-down in the Oval Office.
"Both incoming and outgoing presidents are fully aligned on the importance of releasing the hostages and the urgency," one of the family members said outside the West Wing.
They’re calling on the incoming Trump administration to use these next two months to "take action immediately" with the current national security team to try and secure a hostage release before Inauguration Day.
Earlier today, family members met with the senior staff of Sen. Marco Rubio, who Trump has tapped to be his secretary of state. They said they are hopeful to sit down with the senator later this week. Requests have also been made to meet with all of Trump’s national security picks.
They said they’re hopeful that a new administration will put "new thoughts on the table" since there has been a stalemate for months in trying to secure a deal.
They said they also believe that Trump’s relationship with Prime Minister Benjamin Netanyahu will help get a deal in place "as soon as possible."
This group of family members also met separately with National Security Adviser Jake Sullivan on Tuesday.
