Honoring 9/11 victims on this Patriot Day

Never forget. That is the slogan sometimes used when referring to the terrorist attacks that occurred on September 11, 2001. 

Today is Patriot Day, a national day of mourning to remember the 9/11 attacks. 

Members of Al-Qaeda carried out the largest terrorist attack on U.S. soil by hijacking four planes on 9/11, ramming two into the World Trade Center, one into the Pentagon, and another in a Pennsylvania field. 

Many memorial ceremonies are organized to honor the nearly three-thousand people who died in the attacks. 

Thousands of others were injured.

Patriot Day is not a federal holiday; schools and businesses remain open today. 

The U.S. flag will fly at half-staff at all U.S. government buildings throughout the world.
