Lebanon announced the reopening of the Masnaa border crossing with Syria starting Wednesday evening, state media said, after it had been closed for several days due to an Israeli threat to target it.

The Israel-Hezbollah conflict in Lebanon is not covered by a temporary ceasefire deal between Washington and Tehran, U.S. public broadcaster PBS quoted President Donald Trump as saying Wednesday.

The U.S.-Iran ceasefire does not apply to Israel's strikes against Hezbollah in Lebanon, White House press secretary Karoline Leavitt told Axios, contradicting statements from Iran and the Pakistani mediators.

Iranian Foreign Minister Abbas Araghchi raised "ceasefire violations" by Israel with Pakistani mediators on Wednesday, an Iranian ministry statement said, as reports citing senior officials warned that Tehran could pull out of the truce over attacks on Lebanon.

The health ministry said in a preliminary toll that the series of Israeli strikes across Lebanon on Wednesday killed dozens of people and wounded hundreds.

"In a very serious escalation, Israeli warplanes launched a wave of simultaneous airstrikes on several Lebanese areas, resulting in, in an initial count, dozens of martyrs and hundreds of wounded," the ministry said in a statement.

A Hezbollah official said the militant group backed by Iran is giving a chance for mediators to secure a ceasefire in Lebanon.

In the meantime, the official said, "We have not announced our adherence to the ceasefire since the Israelis are not adhering to it."

Prime Minister Nawaf Salam on Wednesday called on his country's friends to help put an end to Israeli attacks following a series of deadly strikes across the country.

In a statement, Salam said that while Beirut "welcomed the agreement between Iran and the United States and intensified our efforts to reach a ceasefire agreement in Lebanon, Israel continues to escalate its attacks".

The Israeli military chief of staff said on Wednesday that Israel will continue to "utilize every operational opportunity" to strike Hezbollah after the military said it struck more than 100 targets within 10 minutes across Lebanon, the largest wave of strikes since March 1.

Lt Gen. Eyal Zamir said Israel will continue striking Hezbollah to protect Israel’s northern residents, who have come under heavy fire from Hezbollah. The Israeli strikes caused panic during Lebanon’s afternoon rush hour as plumes of black smoke rose over several civilian neighborhoods across the capital.

Israel launched a series of strikes on Beirut on Wednesday, hitting several parts of the capital as well as its southern suburbs.

Loud booms could be heard throughout the city and smoke was rising from several points.

French President Emmanuel Macron said the ceasefire agreement between the U.S., Israel and Iran "fully includes Lebanon," which is in opposition to the stance taken by Israel as it continues an offensive there.

Macron said the inclusion of Lebanon in the deal is "a good and even essential thing."
