Israel-Gaza-Lebanon live updates: American hostage's father makes plea to Biden and Trump

Hezbollah allies on Wednesday praised the group for securing its ceasefire deal with Israel.

In a press conference Wednesday morning, Iranian Foreign Ministry spokesperson Esmaeil Baqaei said Tehran supports "ending Israel's aggression against Lebanon as a part of the ceasefire."

Iran -- the founder and director of the so-called "Axis of Resistance" of which Hezbollah is a key element -- maintains "unwavering support for the Lebanese government, people and resistance," Baqaei said.

Hamas, meanwhile, said in an official statement that it welcomed the ceasefire and praised Hezbollah's support of Palestinians, as well as the "great sacrifices" of the group's members including late leader Hassan Nasrallah.

Israel's acceptance of the deal, Hamas added, is a "milestone" in "destroying" Israeli Prime Minister Benjamin Netanyahu's "illusions of changing the map of the Middle East by force and his illusions of defeating or disarming the resistance forces."

Yemen's Houthis -- who have been attacking shipping and launching long-range strikes into Israel -- also praised Hezbollah's "steadfastness," framing the ceasefire deal as an Israeli defeat.

"The conflict with the Zionist enemy is an inevitable conflict and the wars with it are rounds in a conflict that will inevitably end with its demise," the Iran-backed group said in a statement.

The Israel Defense Forces said its warplanes bombed "dozens" of Hezbollah targets across Lebanon in the hours leading up to the Wednesday morning ceasefire.

The IDF said in a post to social media that the targets included "Hezbollah command centers, launchers, weapons storage facilities and terrorist infrastructure sites in Beirut, Tyre and Nabatieh."

The IDF also struck "several smuggling routes between Syria and Lebanon, which were used by Hezbollah to smuggle weaponry," the force said.

The Lebanese Armed Forces said in a Wednesday morning statement that it was "taking the necessary measures to complete the deployment in the south as mandated by the Lebanese government" after the ceasefire deal with Israel came into effect.

The ceasefire agreement stipulates that Lebanese troops will take up positions in the south of the country and prevent the return of Hezbollah forces -- who are expected to withdraw north of the Litani River -- to the area.

LAF commander General Joseph Aoun met with caretaker Prime Minister Najib Mikati on Wednesday to discuss the security situation in the south of the country, a statement posted to Mikati's X channel said.

The LAF is expected to deploy around 5,000 troops to the area as part of the 60-day ceasefire. United Nations Interim Force in Lebanon soldiers will remain in southern Lebanon to assist.

Israeli troops are expected to withdraw from their positions in south Lebanon in phases during the same timeframe.

Lebanese parliament speaker Nabih Berri said in a Wednesday address that the nascent ceasefire between Israel and Hezbollah is "a test for all Lebanese, from all sects, to save their country and protect its constitutional institutions."

Berri -- the leader of the Hezbollah-allied Amal Movement who has been negotiating on Hezbollah's behalf -- said the Lebanese "people were able to neutralize the effects of the Israeli aggression" and saluted late Hezbollah leader Hassan Nasrallah, who was killed in an Israeli airstrike in September.

"We call on all our displaced people in all our regions and the sister countries that hosted them to return," Berri added. "We are in dire need of national unity among all the Lebanese people."

Berri called for the "speedy election" of a new Lebanese president and thanked all those "who contributed to the ceasefire."

Hezbollah is yet to issue any official statement on the ceasefire, which went into effect at 4 a.m. local time Wednesday.
