Some of the thousands of surface-to-air missiles that have gone missing since the collapse of the Gadhafi regime in Libya have now turned up just miles from the Israeli border.

U.S. officials say there were 20,000 Russian-made anti-aircraft missiles in Libya before the uprising, and thousands have disappeared in the looting of Moammar Gadhafi’s arm caches. According to the Washington Post, many of those Russian-made anti-aircraft weapons are being sold in Egyptian black markets, and so many are available the price has dropped from $10,000 to $4,000…

The missiles, four to six-feet long and Russian-made, can weigh just 55 pounds with launcher. They lock on to the heat generated by the engines of aircraft, can be fired from a vehicle or from a combatant’s shoulder, and are accurate and deadly at a range of more than two miles.
