An apparent terrorist attack along Beirut airport road was accidentally aborted Wednesday less than two hours before the scheduled arrival of Arab League Secretary General Amr Moussa to resume efforts aimed at implementing an Arab initiative to end Lebanon's ongoing crisis. A senior security source, speaking on condition of anonymity, told Naharnet a police patrol had just erected a checkpoint a few hundred meters from the entrance to the airport premises when an unidentified man riding a motorcycle and heading towards the checkpoint suddenly slammed on the brakes and made a "sharp U turn, dropping an object." Members of the patrol shouted at the motorcyclist and rushed to check the object that "turned out to be a Grenade Launcher (Energa)." The unidentified motorcyclist drove " on the wrong side of the road and then turned left towards the Raml al-Ali district where he vanished," the source said. After checking the Grenade Launcher it turned out to be "of the same type used in previous attacks against police barracks," he explained. The encounter occurred at 12:50 local time, Moussa's plane touched down at 2:30 pm.
