"Over the weekend, Hezbollah launched approximately 200 projectiles toward the State of Israel and IDF troops, in a clear and ongoing violation of the ceasefire understandings," the official said, in a statement to AFP.

Fighting between Israeli forces and Hezbollah has continued even as envoys from both the countries agreed on Friday to extend the ceasefire by another 45 days.

In recent weeks, Hezbollah has repeatedly deployed low cost fibre-optic first person view (FPV) drones targeting Israeli forces, posing a new challenge for the Israeli military.

"Today, we are facing the challenge of neutralising FPV drones," Prime Minister Benjamin Netanyahu said at the opening of the weekly cabinet meeting on Sunday.

"This is a specific type of threat ... my directive to the team is to find a solution for this, and for the next threat that will come."

Lebanon got dragged into the Middle East war after Hezbollah fired rockets at Israel on March 2, in response to a joint US and Israeli military campaign against Iran.

In retaliation, Israel invaded southern Lebanon and has continued to strike Hezbollah targets across the country.

Israeli attacks since the start of the war have killed more than 2,900 people in Lebanon, including more than 400 since the truce began on April 17, according to Lebanese authorities.

The Israeli military says it has lost 20 soldiers and one civilian contractor in southern Lebanon since the war began.
