Just how exactly was Hezbollah armed?

From Tehran, but with express approval of the Lebanese government.

TWELVE trucks crossed the Syrian border into Lebanon and rumbled south. When they were stopped at a checkpoint a few days later, the Lebanese Armed Forces found the trucks were brimming with ammunition and weapons, including Katyusha rockets that have been raining down on Israel since July 12.

What happened next, in this little-reported incident in late January, goes to the heart of the conflict between Israel and Lebanon. The convoy was waved on and travelled unhindered to its final destination: Hezbollah terrorists in southern Lebanon.

The Lebanese army said the transportation and storage of ammunition belonged to the "resistance". Once inside Lebanon it was subject to a ministerial policy statement of the Lebanese Government, which considers the "resistance" to be legitimate.

"As the Government of Lebanon has confirmed, the Lebanese Armed Forces has thus not been authorised to prevent further movement of the ammunitions, which had been a common practice for more than 15 years," UN Secretary-General Kofi Annan said in a letter to the Security Council in April. "Hezbollah publicly confirmed that the arms were destined for the group."

It's this uninterrupted flow of weapons, mostly made in Iran, under the nose of the Lebanese Government, that has allowed Hezbollah to stockpile some 12,000 Katyusha rockets. Over the past 29 days of conflict, Hezbollah has fired more than 3000 rockets into Israel.

Syrian-made rockets, including mid-range 220mm units, have also fallen on Nazareth and Haifa, Israel's third-largest city. The warheads were filled with ball bearings to maximise civilian casualties.
