Queen Máxima arrives in Argentina for her sister Inés Zorreguieta’s funeral

Queen Maxima of Holland has attended the funeral of her sister, Inés Zorreguieta, in Argentina.

The news broke earlier this week that the 33-year-old had passed away after reportedly taking her own life following a battle with depression.

Zorreguieta's death was confirmed by the Dutch Royal House communications department, who also said the Queen, 47, is "very shocked and very sad" by the news and has cancelled all forthcoming events.

Argentine-born Queen Máxima was accompanied by her husband King Willem-Alexander and their three children Princesses Amalia, 14, Alexia, 12, and Ariane, 11 to the sad event, where a small group of mourners were seen carrying the coffin through Memorial park in Pilar, before gathering to pay their respects.

According to Dutch broadcaster NOS, only the closest family members attended the event.

Buenos Aires-born Maxima had a close relationship with her youngest sister, who was bridesmaid at her wedding to then-Crown Prince Willem-Alexander in 2002.

She's also a godmother to Princess Ariane, now 11 - the third and youngest daughter of the Dutch royals.

Zorreguieta was a psychologist who worked for an office on social policies at the president's office.

The queen was due to attend a musical event, Holland Festival, this week but she will not be making an appearance. She will also not join her husband Willem-Alexander on their tour of Estonia, Lithuania and Latvia next week.
