More Australian athletes may withdraw from the Commonwealth Games in Delhi, Australia's sports minister has said.
Mark Arbib said the head of Australia's Commonwealth Games Association had told him he expected a number to follow world discus champion Dani Samuels.
Samuels withdrew on Tuesday, citing security and health concerns.
Her decision came after the head of the Commonwealth Games federation fiercely criticised India over the facilities it was providing for athletes in Delhi.
Michael Fennell, president of the Commonwealth Games Federation, said advance teams had been shocked by what they had seen at the athletes' village, where toilets were ****** and flats unfinished.
A spokesman for the local organising committee said foreign officials might have "different standards of hygiene", but also promised that conditions would be improved before the Games opened on 3 October.
In a separate development on Tuesday, a pedestrian bridge connected to the main Jawaharlal Nehru Stadium stadium collapsed, injuring 27 workers, five of them seriously.
Clearly, the 'Indian way' hasn't worked - and the Games are turning out to be India's bonfire of vanities
Raj Kumar Chauhan, Delhi's minister for development, said the accident occurred when workers were trying to pour concrete into a clip at the base of the bridge, and the clip was loosened.
