  • Student Demonstration Erupts in Violence

1. Approximately 7000 students gathered this afternoon at Casco de Santo Tomas campus of National Polytechnic Institute (IPN), in accordance plans announced June 2 for demonstration and march in support of students and faculty at autonomous University of Nuevo Leon.

2. Information still coming in and reports conflicting but it appears police (one source says plain-clothed “halcones”) moved to break up meeting which had over-flowed campus, shortly after 5:00 p.m. shooting started (police claim by students) with resulting estimated two killed and 30 wounded, of which, one a newsman. Sporadic shooting continues as of this report, although students are now reported breaking up into small groups and moving off campus.

3. Our present information is that Army was on alert but did not become involved in action at IPN. UNAM and other campuses apparently quiet.
