LEBANON, Pa.—Two firefighters are hurt and 10 people have been displaced after a fire at an apartment building in Lebanon.

The blaze broke out at the home around 6:30 p.m. Thursday and quickly spread. Fire Commissioner Duane Trautman says it apparently started in a kitchen trash can in a second-floor apartment. Four apartments in the building were damaged.

Officials say one firefighter was hurt in a fall, but it wasn't immediately clear how the second was injured. Both are expected to recover.

The cause of the fire is under investigation.
