Has Ban Ki-Moon something to say about this? Is it going to investigate this or investigations are only made when Israelis are involved?

Syria has transferred long-range Scud missiles to the Lebanese Shiite militant group Hezbollah, Israeli and U.S. officials alleged, in a move that threatens to alter the Middle East's military balance and sets back a major diplomatic outreach effort to Damascus by the Obama administration.
Israeli President Shimon Peres on Tuesday publicly charged President Bashar Assad's government with transferring Scud missiles to Hezbollah's forces inside Lebanon. Syria and Hezbollah both denied the charges. But the allegations already are affecting U.S. foreign policy: Republicans pressed on Capitol Hill to block the appointment of a new American ambassador to Damascus, according to congressional officials. The White House said it was pressing ahead.
The Scuds are believed to have a range of more than 435 miles—placing Jerusalem, Tel Aviv and Israel's nuclear installations all within range of Hezbollah's military forces. During a monthlong war with Israel in 2006, Hezbollah used rockets with ranges of 20 to 60 miles.

The Scuds could be made with North Korean or Russian technology. Anyway, in 2005, Hizbullah was using already Russian missiles sold to Syria, although till now they weren't long-range ones.

Hizbullah's terrorists are trying to infiltrate themselves in several other countries, specially from South America and in the US.

Federal authorities have identified Hizbullah-aligned cells in several cities in the United States. In February 2010, four Florida men were charged in a plot to relay millions of dollars to Hizbullah through a shopping center in Paraguay. The suspects were said to have been working with Mohammed Yusef Abdullah, identified as Hizbullah's main liasion in South America.

 Europe drug trade is funding Hizbullah, while on the other hand it is rumoured that Russian FSB (ex-KGB) helped Hizbullah busting Israeli spy rings.
