Americans are marking 24 years since the Sept. 11, 2001, attacks with solemn ceremonies, volunteer work and other tributes honoring the victims.
Some 1,106 victims, or 40% of those who died, remain unidentified.
27-year-old Akayed Ullah, a Bangladeshi immigrant, will be arraigned in federal court Thursday.
Akayed Ullah's family released a statement saying they were "heartbroken by the violence," but also "outraged at the behavior of law enforcement."
Veronica Chavez describes being frozen in fear at the sound of the explosion, and then running for her life, fearful of a secondary explosion.
The suspect has been identified as 27-year-old Akayed Ullah, who is from Bangladesh and has been in the country for seven years. He reportedly lived at an address in Brooklyn.
