Four people were killed and several others wounded in Israeli drone strikes targeting Mayfadoun in southern Lebanon on Tuesday afternoon, according to a preliminary toll reported by Lebanon's state-run National News Agency (NNA).

Israeli attacks intensified in the Nabatieh area, where a drone first targeted a vehicle in Mayfadoun before striking the area again after residents gathered at the scene. A second vehicle was later targeted in the same area. The attacks in Mayfadoun resulted in the deaths of four people and injuries to several others, according to NNA.

Iran and the United States finalized a peace memorandum of understanding (MoU) on Sunday, which is also expected to end fighting between Israel and Hezbollah in Lebanon.

However, Israeli Prime Minister Benjamin Netanyahu told a press conference on Monday that the Israeli military would remain in the "security zones" it controlled in Lebanon, Syria and the Gaza Strip as long as necessary.

Israeli strikes in the Gaza Strip also continued. Two Palestinians were killed and others wounded in an Israeli airstrike on the Nuseirat refugee camp in the central Gaza Strip on Tuesday, as the evacuation of sick and wounded continued through the Rafah border crossing.

Displaced people return to southern Lebanon

Following news of a US-Iran deal, displaced people began returning to their homes in southern Lebanon despite challenges, UN humanitarians said on Tuesday.

The UN Office for the Coordination of Humanitarian Affairs (OCHA) said some families are cautiously returning to their communities of origin following Sunday's announcement of an agreement between the United States and Iran, which reportedly includes the cessation of hostilities in Lebanon.

According to Lebanese authorities, the number of displaced people hosted in collective shelters has decreased by about 10,000 people over the past four days. In South Governorate, about 2,700 people reportedly left collective shelters on Monday, OCHA said.

However, the office said it remains unclear whether these movements represent temporary visits to inspect their property or permanent returns.

OCHA said that violent incidents in southern Lebanon continue to be reported, affecting people's ability to move safely.
