Is this in addition to the missiles they admit to having supplied already?
i am not sure
Hizb'allahs Katyusha rockets
Japanese-made Isuzo truck launchers carry Fajr-3 (Arabic for dawn-3) projectiles,
a third generation of Katyusha rockets manufactured by Iran's air force industry.
In October 2002 it was reported that Iranian Zelzal-2 short-range ballistic missiles
had been delivered to Iranian Revolutionary Guard units in the Beka'a Valley in Lebanon.
On August 4, 2006, Syrian-made (Russian made?) 302 mm projectiles were fired
from Lebanon into the northern Israeli town of Afula.
