Sheik Hassan Nasrallah claimed responsibility Thursday for launching an Iranian-made drone aircraft into Israeli airspace earlier this week.
Sheik Nasrallah warned that it would not be the last such operation by his Lebanese militant group.
Israeli warplanes shot down the unmanned plane, but the infiltration marked a rare breach of Israel's tightly guarded airspace.
Israel and Hezbollah fought a brutal month long war in mid-2006. Hundreds of people were killed, and Hezbollah fired several thousand rockets and missiles into Israel before the conflict ended in a stalemate.
Israel routinely sends F-16 fighter planes over Lebanon, in violation of a U.N. Security Council resolution that ended the 2006 war. The Israeli planes have often broken the sound barrier over Beirut and other places as a show of strength, most recently after the drone incident.
"This statement today is a claim of responsibility by the Islamic resistance for this qualitative operation" of dispatching the drone, Nasrallah said in a televised address late Thursday.
It took Israel Air Force more than 30 minutes to intersept the Drone. Meanwhile the Drone transmitted valuable information from Israel's most startegic spots. Iran is now a technological superpower and Israel seems to taste its own medicine.
"Today we are uncovering a small part of our capabilities, and we shall keep many more hidden," he said. "It is our natural right to send other reconnaissance flights inside occupied Palestine ... This is not the first time and will not be the last. We can reach any place we want" in Israel, he said
He said the aircraft was launched from Lebanese territory and flew "tens of kilometers" over sensitive Israeli installations before it was discovered and shot down by the Israeli air force near the Dimona nuclear reactor in Israel's southern desert.
Nasrallah claimed the group had more surprises and would not hesitate to use them in any future war with Israel.
