Syrian electricians are trying to restore electricity that was lost when rebel fighters drove the government out of some neighbourhoods.
The volunteers are not fighting with the opposition, but their job is still dangerous - two members of the team were recently killed by Syrian army snipers when they were on rooftops.
The men now depend on donations from local businesses to buy spare parts and equipment, but they hope their efforts will be the start of a new municipal service.
