Firefighters were called to fires involving wheelie bins and cars, as isolated outbreaks of civil disturbance took place, a brigade spokesperson told FIRE.
Two women were rescued by ladder from a house in Lawrence Road, Wavertree, after smoke from car fires filled their house and set off the smoke alarm.
Assistant Chief Fire Officer Dan Stephens said: "It's very sad to see this type of behaviour in Liverpool and putting the lives of the public and our fire crews in danger.
"Merseyside Fire and Rescue Service will be in the community today just to reassure people that we will be attending any incidents where lives and property is at risk and offering safety advice."
