Several dozen students briefly occupied Dutton Hall, an administration building on the University of California Davis campus, yesterday afternoon in protest against Israeli attacks on Gaza. The protest came one day after the first anniversary of last year’s notorious pepper-spraying of UC Davis activists by campus police.

According to the California Aggie, the UC Davis student newspaper, tempers flared between protesters and pro-Israel students at the occupation in two separate incidents.

The paper says that when demonstrators saw one student recording the action on her camera phone they approached her and “two neighboring Israeli students,¬†yelling ‘Death to Israel’¬†and ‘Fuck Israel’ until they left.” Later, the paper reported, a demonstrator “grabbed [another student] by the shirt collar and raised a fist” after he “vocalized disagreement with one of the signs in the room.”

It’s not clear whether Aggie reporters witnessed either of the two incidents. The paper’s tweets from the scene mentioned only “heated … talk,” not intimidation or physical confrontation.

Update | Aggie editor and article author Janelle Bitker says she and another Aggie staffer witnessed both incidents.
