Residents of Beirut’s southern suburbs have been scrambling to make contingency plans since an Israeli airstrike on an apartment building in a busy neighborhood killed a top Hezbollah commander and touched off fears of a full-scale war.

For most, that means moving in with relatives or renting homes in Christian, Druze or Sunni-majority areas of Lebanon that are generally considered safer than the Shiite-majority areas where the Hezbollah militant group has its main operations and base of support.

But for a small number, plan B is a move to neighboring Syria.

Although Syria is in its 14th year of civil war, active fighting has long been frozen in much of the country. Lebanese citizens, who can cross the border without a visa, regularly visit Damascus. And renting an apartment is significantly cheaper in Syria than in Lebanon.
