'Deeply shocking' swastika graffiti has been found inside an Oxford college, its Principal has said, as pro-Gaza protesters at the elite university clashed with police. Sir Malcolm Evans, who leads Regent’s Park College, told students 'appropriate action will be taken should we become aware of the identity of those responsible'. It is understood the Nazi symbols were found on the walls of two toilet cubicles next to the college's Hall - its dining room - leaving Jewish students 'deeply upset'.
