French police target Islamist networks after teacher's beheading

French police have conducted a series of raids targeting Islamist networks, three days after the beheading of a history teacher who had shown his pupils a cartoon of the Prophet Mohammed. Interior Minister Gerald Darmanin vowed there would be "not a minute's respite for enemies of the Republic", after tens of thousands took part in rallies countrywide on Sunday to honour teacher Samuel Paty and defend freedom of expression.
