The IDF has yet to confirm or deny the reports

The Israel Air Force (IAF) overnight Wednesday allegedly attacked a weapons shipment to Lebanese-based militant group Hezbollah, north of Damascus on the Syria-Lebanon border, according to reports.

Arab media reported that the IAF attacked a military outpost in El Ktaife, a suburb of Damascus, in an airstrike executed from Lebanese airspace.

According to Syrian media, the Israeli aircraft targeted a convoy belonging to the Syrian army that was carrying weapons to the Hezbollah.

The pro-governmental Masdar news service said that the aircraft flew first through Lebanon and then into Syria.

There were no injuries reported.

On Monday, the Lebanon-based Hezbollah militant group Hassan Nasrallah, warned that it would not keep any "red lines" in a future war with Israel, repeating threats to attack sensitive targets such as its nuclear reactors and chemical plants.

"In the face of Israel’s threats to destroy Lebanon’s infrastructure, we will not abide by red lines, especially regarding Haifa’s ammonia and the nuclear reactor in Dimona," Nasrallah said during an interview with Iran's state-run IRNA television network.

A Syrian military source confirmed the attack to news site Al-Order, but IDF has yet to confirm or deny the reports.

In 2006 Israel fought a devastating war with the Shiite militia Hezbollah and closely monitors the group's activities.

With its formidable arsenal of missiles trained on the Jewish State, Hezbollah remains the most serious military threat facing Israel, a national security think tank claimed in a report released last month.

Israel's military believes Hezbollah has between 100,000 and 120,000 short- and medium-range missiles and rockets, as well as several hundred long-range missiles, with the medium-range missiles capable of reaching Tel Aviv.
