Israeli strikes on Tyre in southern Lebanon killed at least 13 people just before the 10-day ceasefire with Israel took effect at midnight, a city official said on Friday.

The official, who asked not to be identified, said another 35 people were injured, and emergency workers were still searching the rubble for another "15 missing".

Hezbollah said Friday that it was keeping its "finger on the trigger" in case of any Israeli violations of a ceasefire that went into effect overnight.

In a statement, the Iran-backed movement said it had carried out "2,184 military operations" against Israel and its troops inside Lebanon, adding: "The fighters will keep their finger on the trigger because they are wary of the enemy's treachery."

Iran's foreign ministry welcomed on Thursday the truce agreed between Israel and Lebanon, calling it part of the earlier two-week ceasefire deal struck between the Islamic republic and the United States to pause the Middle East war, state media reported.

Ministry spokesman Esmaeil Baghaei "welcomed the announcement of the ceasefire in Lebanon and noted that the cessation of the war in Lebanon was part of the ceasefire understanding between Iran and the United States, mediated by Pakistan", state news agency IRNA posted on Telegram.

A ten-day ceasefire deal agreed between Lebanon and Israel took effect on Friday, as U.S. President Donald Trump said he was trying to set up the first-ever face-to-face meeting between the leaders of the two countries.

The truce comes as Washington steps up efforts to reach a deal to end the war with Iran, with Tehran insisting a Lebanon truce must be part of any agreement.

French President Emmanuel Macron on Friday said he was concerned that a ceasefire between militant group Hezbollah and Israel "may already be undermined by ongoing military operations."

"I call for the safety of civilians on both sides of the border between Lebanon and Israel," he said on X. "Hezbollah must lay down its arms. Israel must respect Lebanese sovereignty and end the war," he added.

European Commission president Ursula Von Der Leyen welcomed a 10-day ceasefire declared Thursday between Israel and Lebanon that was announced by U.S. President Donald Trump.

"This is a relief, as this conflict has already claimed far too many lives," von der Leyen wrote on X, adding that it must lead to "permanent peace".

U.S. President Donald Trump said Thursday he expected Israeli Prime Minister Benjamin Netanhyahu and President Joseph Aoun to visit the White House in coming days, after the U.S. leader announced a ceasefire between Lebanon and Israel.

"As of two hours from now, we have a ceasefire with Israel and Lebanon. And that'll be great. And they'll be meeting -- probably coming to the White House -- over the next four or five days," Trump told reporters.

Israeli rescue services said on Thursday that one person was seriously injured in northern Israel after shelling from Lebanon that came less than two hours before the start of a truce agreed with Lebanon.

Israeli Prime Minister Benjamin Netanyahu said Thursday that the ten-day ceasefire with Lebanon offered an opportunity for a "historic peace agreement" with Lebanon, but insisted that the disarmament of Hezbollah remained a precondition.

U.S. President Donald Trump said Thursday that Iran has agreed to hand over its store of enriched uranium and that the two sides were "close" to a peace deal to end the war that has engulfed the Middle East.
