The “game changing” weapons destroyed in an Israeli airstrike Friday before they could reach Hizbullah were sent by Iran, the New York Times reports, citing senior American officials.

The strike reportedly targeted Fateh-110 missiles. The Fateh-110 has a range of up to 300 kilometers.

Syrian sources gave the New York Times similar information, saying that Iran had sent arms and rockets to Damascus International Airport and planned to ship them on to Hizbullah.

A diplomatic source in Lebanon previously told the AFP news agency that the airstrike destroyed surface-to-air missiles delivered by Russia.

Israeli experts have warned in recent months that Hizbullah may already have chemical weapons, but have noted that the group so far lacks a delivery system that would allow it to make use of its arsenal.

Israel has refused to officially comment on Friday’s airstrike. A statement Friday said only, “Israel is determined to prevent the transfer of chemical weapons or other game-changing weaponry by the Syrian regime to terrorists, specifically to Hizbullah in Lebanon.”
