Actress Helena Bonham Carter is mourning the loss of four relatives who were killed in a bus crash while on safari in South Africa, People magazine reported Saturday.

The victims of the tragedy included the 14-year-old son of the actress’ cousin, Fiona Bonham Carter, the boy’s maternal grandmother, Brenda Bonham Carter, and his stepfather and aunt, People reported.

Fiona Bonham Carter, 51, suffered a broken collar-bone and her other son reportedly suffered whiplash.

The accident took place when the vehicle lost control and overturned on a road near the Welgevonden game reserve, People said.

A rep for Bonham Carter, who has starred in such films as “Charlie and the Chocolate Factory” and "Sweeney Todd,” had no comment on the situation Sunday. Bonham Carter and her husband, director Tim Burton, welcomed their second child Nell in December.
