Mexico City officials say at least two people have died in a shooting following a dispute on the campus of the nation's vast National Autonomous University.

The university says the two people involved are not part of the university community, but hasn't identified them.

The city prosecutor's office says two men aged 20 and 29 died at a hospital after Friday's incident, which occurred near the Department of Accounting and Administration.

Both institutions say they're investigating.

The university has about 350,000 students, though many of them attend school at sites outside the main campus, which is a UNESCO world heritage site.
