Syria has long supplied Hezbollah with other weapons, including missiles and antitank rockets.
Six of the seven people killed were traveling in a car when it was hit by an antitank missile.
One of the five men held a powerful East German antitank weapon.
The heaviest weapons, such as antiaircraft and antitank missiles, came from around the capital itself.
Heavy smoke screens hid the moving forts from the German antitank guns.
