TEHRAN, Oct. 9 (Xinhua) -- An Islamic Revolutionary Guard Corps (IRGC) general said the fact that an unmanned aerial vehicle recently penetrated into Israeli airspace shows the vulnerability of Israel's air defenses, Tehran Times daily reported Tuesday.

According to media reports on Saturday, the Israeli military announced in the day that a warplane of Israel had shot a drone down near the occupied West Bank in the southern country.

The Israeli military did not say where the drone came from but some unofficial remarks within Israel alleged that it belonged to Iran "launched by (the Lebanese Shi'ite group of) Hezbollah."

During a press conference in Tehran on Monday, Brigadier General Jamaloddin Aberoumand, the deputy coordinator of Iran's IRGC, said: "In view of the fact that they (the Israelis) have announced that the unmanned aerial vehicle had penetrated about 100 kilometers into the occupied territories shows that the Zionist regime suffers from many weaknesses," According to Tehran Times.

Aberoumand also said the incident indicated that Israel's Iron Dome and its anti-missile defense system "are not very efficient and lack the required capability."

The IRGC commander did not confirmed that the drone was Iranian or whether it is launched by Hezbollah.

The West and Israel suspect that the Iranian nuclear program, which the officials of the Islamic republic insists is "peaceful", may have military dimensions.

The United States and Israel have not ruled out the possibility of striking Iran's nuclear facilities. The Islamic republic has threatened that it will retaliate if its nuclear establishments are hit.
