On Sunday, flags will be at half-staff all over the United States.
In honour of the National Fallen Firefighters Memorial Service, President Joe Biden gave the order to lower the flags.
This means that all U.S. and state flags will be flown at half-staff until the sun sets on Sunday, October 9.
The National Fallen Firefighters Foundation will honour those who have died with a memorial service in Emmitsburg, Maryland, on Sunday at 10 a.m. ET
