A team of Iranian experts carefully analyzed Lebanese targets demolished by Israel in the immediate aftermath of the Second Lebanon War to gain a better understanding of Israeli assault strategies and ammunition capabilities, a senior Iranian defense official announced on Monday.

“After Hezbollah’s 33-day war, we sent a team to Lebanon and studied the models of Israel’s assault on the Lebanese buildings and collected 5,000 images of all the destroyed buildings,” Civil Defense Organization head Gholam Reza Jalali said, according to the semi-official Fars News Agency.

Speaking at a conference in Tehran dedicated to the defense strategy of the Islamic Revolution Guards Corps (IRGC), Jalali said the damage sustained to Lebanese targets in 2006 had more to do with the engineering strategies the IDF employed than the strength of their artillery.

Jalali also said the Iranian military has adapted its defensive strategies in light of a changing security landscape.

“Threats against us changed after the US presence in the region and invasion against Iraq,” he said.

In October 2013, Jalali said increased efforts to secure Iran’s nuclear facilities have been “a thorn in the side” of the Islamic Republic’s enemies.

“By designing absolutely safe infrastructures and facilities in Fordo and Isfahan’s UCF (Uranium Conversion Facility), the civil defense has put a thorn in the side of enemies, namely Israel and the US,” he said, according to the Tasnim news agency.

Iran and world powers will hold technical talks next week in Vienna ahead of a political meeting to negotiate a comprehensive nuclear deal, a top Iranian negotiator said Sunday.

Iran and the P5+1 group of world powers agreed last week on a timetable and framework for the negotiations for an accord that would allay Western concerns about Iran’s nuclear program in return for the lifting of crippling sanctions.
