Iranian and Syrian officers were reportedly training the Hizbullah operatives in using the new missiles and in operating early warning systems intended to alert the group of Israeli jets.
The Jerusalem Post could not confirm the report.
The Kuwaiti article comes days after Israel's Ambassador to the UN Gabriela Shalev called on Tuesday for an investigation by UN peacekeepers on an explosion in Tayr Filsay in southern Lebanon, after a weapons cache exploded in the home of a Hizbullah operative on Monday night.
In a letter of complaint sent to Secretary-General Ban Ki-moon and the president of the Security Council, Le Luong Minh of Vietnam. Shalev said Israel has "considerable" reason to believe the house where the explosion took place served as an arms storage facility for Hizbullah.
Shalev also said that in the aftermath of the explosion, Hizbullah operatives sealed off the area and attempted to remove evidence.
Following the blast in Tyre, President Shimon Peres said that Hizbullah was turning Lebanon into a "powder keg."
"Hizbullah is endangering Lebanon just like Hamas is endangering the Palestinian people," said Peres. "From our point of view, we can make peace with Lebanon, there is no reason why not," he added, saying the country could be the Switzerland of the Middle East.
