Israel and the Iran-backed group have been regularly trading fire in the country's south despite a ceasefire, which was extended by Israeli and Lebanese authorities last week.

"A short while ago, IDF surveillance identified two armed individuals moving in a suspicious manner hundreds of meters from Israeli territory, in southern Lebanon," the Israeli military posted on Telegram.

"Following their identification and continuous monitoring by the IDF, the armed individuals were struck and eliminated in an aerial strike," the post said.

Since a truce began on April 17, Israel has continued to launch strikes, carry out demolitions and issue evacuation orders in south Lebanon, saying it is targeting Hezbollah, which has also kept up attacks.

Hezbollah launched rockets at Israel on March 2 in retaliation for the killing of Iran's supreme leader in US-Israeli strikes.

Israel responded with a massive series of airstrikes and a ground invasion in the country's south, where its troops are operating inside an Israeli-declared "yellow line" running around 10 kilometres (six miles) inside Lebanon along the border.

Lebanon's health ministry said Thursday that Israeli attacks have killed at least 3,089 people since the wider regional war began.

Israel's military has reported the death of 22 personnel during the fighting.

Last week the fragile temporary truce was extended for 45 days following a third round of direct talks between Lebanese and Israeli representatives in Washington, discussions that Hezbollah staunchly opposes.
