Iran's ambassador to Pakistan deleted a social media post saying an Iranian delegation would arrive in Islamabad on Thursday night, a move an embassy official later told AFP had been sent prematurely.

U.S. President Donald Trump will continue to discuss with Israeli Prime Minister Benjamin Netanyahu the idea of including Lebanon in an Iran war ceasefire deal, his spokeswoman said Wednesday.

Israel's Prime Minister Benjamin Netanyahu said Wednesday that Israel remains prepared to confront Iran if necessary, despite a truce reached between the United States and Iran.

Hezbollah said Wednesday it has a "right" to respond to Israel's deadly wave of strikes across Lebanon, which authorities said left at least 112 people dead and more than 800 wounded.

The Israeli military said it struck a Hezbollah commander in Beirut on Wednesday, after Lebanese state media reported that Israel had targeted the Tallet al-Khayyat residential neighborhood in the capital.

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.

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.

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".
