JOHANNESBURG  - A stampede broke out Tuesday as thousands tried to enrol at a Johannesburg university, killing one woman and injuring at least 20 people, university and emergency services officials said. Thousands of people had queued outside the University of Johannesburg after it announced it would accept late applications from those who missed an earlier deadline or who recently became eligible thanks to their exam scores. When the university opened its gates at 7:30 am (0530 GMT) to begin letting applicants in, people in the back of the line started pushing, officials said.
