"I don't know how I'm going to get home. It's bad for them to cut the wires but it is not wrong for them to strike. They need more money."
Daphne Kayster, of Metrorail's marketing and communications department, said the rail operator condemned the violence.
"What is more disturbing is that this strike has nothing to do with Metrorail, yet our customers are forced to bear the brunt of these actions."
