The video purported to show a missile being launched towards a moving armoured vehicle before an explosion sent large clouds of white smoke into the sky.

"The first Kornet anti-tank missile is launched at the target and then, from another position, a second missile is fired to ensure the target is destroyed," a voiceover said.

The target, which Hezbollah identified as a Wolf armoured vehicle, was 1.5 kilometres (one mile) from the Lebanese-Israeli frontier and four kilometres from the launch site of the first missile, Al-Manar said.

Hezbollah on Sunday said its fighters had "destroyed a military vehicle on the road to the Avivim barracks, killing and wounding those inside".

Israel's army said it had responded with around 100 artillery shells after Hezbollah fired two or three anti-tank missiles at a battalion headquarters and military ambulance, hitting both.

Israeli officials refuted claims by the Iranian-backed movement that it had killed and wounded those inside the military vehicle, saying there were no casualties.

Sunday's exchange of fire over the Lebanese-Israeli border came one week after Hezbollah accused Israel of carrying out a drone attack on its southern Beirut stronghold.

On August 24, Israel also said it had carried out strikes in Syria to avert an Iranian drone attack on the Jewish state. Hezbollah said those strikes killed two of its members.

Israel has carried hundreds of strikes in war-torn Syria, mostly against what it says are Iranian or Hezbollah targets.
