ČTK (Česká tisková kancelář) upozorňuje (X), že na jejím zpravodajském webu České noviny byly dnes dopoledne neznámým útočníkem umístěny dva smyšlené texty, které nepocházejí z její produkce. Jde o text s titulkem „BIS zabránila pokusu o atentát na nově zvoleného slovenského prezidenta Petra Pelligriniho“ a o údajné mimořádné prohlášení ministra Lipavského k témuž. Tyto dezinformace byly útočníky zveřejněny i s příslušnými notifikacemi v mobilní aplikaci Českých novin. ČTK ve svém zpravodajském servisu žádnou informaci v tomto znění nevydala.
