Tens of houses were damaged and families fled the town due to the deteriorating situation amid an acute fuel shortage and lack of phone services.
Military reinforcements have been deployed to Radfan in recent months to fight separatist militants who have stepped up their attacks, targeting military posts and public property.
Lahj is one of the southern cities hit by violence where the separatist movement, Al-Harak, continues the anti-government protests that usually turn violent.
