One of the three tigers born at the Los Angeles Zoo last month has suddenly died.

It's unclear what happened, but the cub apparently suffered some sort of head trauma.

The two remaining Sumatran tiger cubs will still be raised by their mother, Lulu, who's had success raising cubs in the past.

Sumatran tigers are critically endangered.
