Surrounded by yellow Hizbullah flags, more than 60 Iranian volunteers set off Wednesday to join what they called a holy war against Israeli forces in Lebanon. The group, ranging from teenagers to grandfathers, plans to join about 200 other volunteers on the way to the Turkish border, which they hope to cross Thursday. They plan to reach Lebanon via Syria on the weekend. Organizers said the volunteers are carrying no weapons, and it was not clear whether Turkey would allow them to pass. A Turkish Foreign Ministry official, speaking on condition of anonymity, would not say Wednesday if Turkey would allow them to cross. Iranians, however, can enter Turkey without a visa and stay for three months.
