China plans 'crackdown' after Covid protests
China's top security agency has called for a crackdown on "hostile forces" after rare protests against Covid rules in Chinese cities at the weekend.
Police officers have flooded now-empty protest sites, with some protesters saying police have contacted them to seek information on their whereabouts.
Meanwhile the country's health officials say lockdowns should be "imposed and eased quickly".
China has recorded record numbers of new cases in recent days.
