South Korean authorities say the death toll from a crowd crush in Seoul will rise.

More than 150 people died when thousands crammed into a narrow alleyway during Halloween celebrations.

Witnesses describe it as a slow and agonising crush with no police in sight, while questions are being raised about the safety precautions organisers had in place.

A 23-year-old Australian woman is among those who have died.

A national day of mourning has been declared.
