A small trash fire briefly delayed Metro trains on the Yellow and Blue lines near the Pentagon on Saturday, authorities said.

There were no injuries or serious disruptions to service.

The debris fire broke out shortly before 5 p.m. in the tunnel between Pentagon City and the Pentagon, forcing operators to hold some trains in their stations until the Arlington County Fire Department could put it out, chief Metro spokesman Dan Stessel said.

By 5:10 p.m. the fire was extinguished, and regular service resumed at 5:13 p.m., he said.
