VIDEO - The IDF on Tuesday released footage showing weapons smuggling at the home of Hezbollah operative Abdel Nasser Issa in the southern Lebanon village of Tayr Filsi, on the outskirts of Tyre.

Issa and his son were reportedly killed Monday evening during an explosion that took place inside their home, which the IDF claims was used to store weapons.

The footage was taken by an IDF drone.

Hezbollah and the Lebanese army denied anyone was killed in the blast, and said it was caused by an exploding shell.

The IDF filed a complaint with the United Nations Interim Force in southern Lebanon, demanding an investigation into the explosion. Army sources said the incident proved that Hezbollah continues to bring weapons and ammunition into southern Lebanon and is hiding them in houses, in violation of Security Council Resolution 1701.

UNIFIL said it was aware of an explosion and was in contact with the Lebanese army. "We are looking into the circumstances of the incident," UNIFIL spokeswoman Yasmina Bouziane said.
