The Duke and Duchess of Cambridge attended a memorial service on June 14 to honor the victims of the Grenfell fire, five years after the tragedy that killed 72 people.

On that day in 2017, a fire broke out in a residential tower in West London, and the organization Grenfell United has since been fighting for policies to ensure safe housing for everyone in the UK.

According to People, the organization organized a multi-faith memorial service this week that took place near the now-derelict building.

The Duke and Duchess, wearing Susanna shirtdresses and Alessandra Ricci slingback pumps (opens in new tab), laid a wreath in honor of the 72 victims.

The Cambridges also spoke to survivors and bereaved families of the horrific event, including many children.

Reflecting on the service on Instagram, the Cambridges wrote, "Five years ago, 72 people tragically lost their lives in the devastating fire at Grenfell Tower.

"Today, a memorial service was held and we, along with the survivors, remembered those who died. We were honored to meet the people of Grenfell United, who play an important role in providing pastoral care to the survivors and advocating for the bereaved so that such a tragic event will never be repeated."

Prince William and Kate Middleton first attended a memorial service for the tragedy in December 2017.

Meghan, Duchess of Sussex, has also repeatedly supported efforts to help the victims. Other public figures such as Beyonce, Jay-Z, and Ed Sheeran have also supported the Justice4Grenfell movement over the years.
