Israeli air strikes have continued to target towns in southern Lebanon despite an agreement between the United States and Iran set to be formally signed on Friday to end the war on all fronts.

Israeli drones carried out three attacks in Tyre that resulted in injuries while a drone also targeted the Bint Jbeil district in Nabatieh, Lebanon’s state-run National News Agency said on Wednesday.

The fighting in Lebanon is considered one of the biggest threats to the framework agreement in the US-Israel war on Iran with Tehran warning that new Israeli strikes on Lebanon and continued occupation of its territory would be regarded as a violation of the deal.

Earlier on Wednesday, Al Jazeera Arabic correspondents on the ground reported that Israeli forces carried out an air strike on the outskirts of Kfar Tebnit, also in the Nabatieh district. They also launched raids on the town of Nabatieh al-Fawqa and shelled the Ali al-Taher heights and the outskirts of the town.

Hezbollah fighters, meanwhile, launched at least 10 rockets towards Israeli forces near Kfar Tebnit.

A day earlier, Israeli attacks killed at least four people in Nabatieh, including in drone strikes on several vehicles.

There has been a reduction in violence since the US-Iran agreement was announced, but attacks have not stopped, Al Jazeera’s Zeina Khodr said, reporting from Beirut.

“Security sources believe that the Israeli army is trying to occupy more ground, especially strategic high ground around Nabatieh,” she said.

“Yes, families have started to return to their villages, but people are worried. They say they don’t trust that Israel will abide by the ceasefire.”

United Nations spokesperson Stephane Dujarric said the number of projectiles fired between Israeli forces and Lebanon fell to 174 on Sunday, compared with 705 the previous Sunday.

Of these, 169 were attributed to Israel and five to Hezbollah, he said.

Lebanon ‘most sensitive issue between the sides’

The situation in Lebanon is one of the main pillars of the US-Iran agreement, Al Jazeera’s Almigdad Alruhaid said, reporting from Tehran.

“As we approach the signing of the deal, it is becoming the most sensitive issue between the sides,” Alruhaid said.

Iran said the Israeli military has violated the ceasefire in Lebanon 84 times in the past two days and warned that Israel should expect “a harsh response” if it does not stop its attacks, he reported.

This came after Iranian Foreign Minister Abbas Araghchi said the withdrawal of the Israeli military from Lebanese territory is one of the core demands right now to move forward with the framework agreement Iran has with the US, Alruhaid said: “So the Iranians say the situation in Lebanon, in particular southern Lebanon, is an integral part of the memorandum of understanding.”

Lebanon was among the top priorities for the Iranians when they started negotiations with US President Donald Trump’s administration, according to Mohammad Eslami from Tehran University.

“Once the Iranians not only retaliated against the Israeli attacks on Dahiyeh and Beirut but also pre-emptively attacked Israeli territory, they showed right from the outset they are determined and very serious about supporting Lebanon, the Lebanese people, the Lebanese government and the resistance factions in Lebanon,” Eslami told Al Jazeera.

Israel’s invasion akin to ‘war crimes’

Meanwhile, the human rights group Amnesty International said on Wednesday that the Israeli army’s mass forced displacement orders in Lebanon amount to war crimes under international law.

“In parts of southern Lebanon, the Israeli military’s forced displacement of civilians and prevention of their return amounts to unlawful transfer – which is a war crime,” Amnesty said in a statement.

The Israeli army has “radically expanded” its use of such orders, displacing hundreds of thousands of people across Lebanon, it said.

“Instead of forcibly uprooting communities and designating entire swathes of Lebanese land as ‘no-go zones’ for civilians, Israeli forces must immediately withdraw from Lebanese territory,” said Kristine Beckerle, Amnesty International’s deputy regional director for the Middle East and North Africa.

The Israeli military declared about 4.6 percent of Lebanon as a “no-go zone” on November 28, 2024, a day after a previous ceasefire took effect, Amnesty noted.

This year, just three days after an April 17 ceasefire announcement, the restricted area was expanded to about 6 percent of the country, and residents were ordered not to return to villages previously home to tens of thousands of civilians.

Lebanese officials said Israel, which has been carrying out a large-scale offensive in the country since March 2, has killed more than 3,800 people, wounded 11,850 and displaced more than one million.
