The Jerusalem Post reports: “Two Columbia University schools were vandalized by anti-Israel activists on Wednesday afternoon, according to the institution and activist groups, with cement flushed down toilets and a building facade sprayed with red paint.

In a video and manifesto supposedly anonymously submitted to activist group Unity of Fields by vandals, the alleged perpetrators revealed that they flushed concrete down the toilets in Columbia’s School of International and Public Affairs to cement ‘the sewage lines of the entire building, forcing them to shut down business-as-usual.’

The facilities were vandalized with graffiti that included ‘disturbing, personal attacks,’ according to Columbia..

The accompanying manifesto claimed that it had attacked the school because it had expelled an anti-Israel student activist. The vandals mentioned the school’s dean and former IDF intelligence soldier Keren Yarhi-Milo as a ‘killer.’ 

 The vandals also blamed New York Police Department Intelligence and Counterterrorism Deputy Commissioner Rebecca Weiner, who according to her LinkedIn is also adjunct assistant professor at the school, for the clearing of the April activist occupation of Columbia’s Hamilton Hall…”
