Thailand has announced an expansion of coronavirus restrictions that include travel curbs, mall closures and a night-time curfew to three more provinces after the country reported a third consecutive day of record case numbers.

The country reported 11,397 infections and 101 deaths, bringing the cumulative total to 403,386 cases and 3,341 fatalities, the vast majority from an outbreak since early April that is being fuelled by the highly transmissible Alpha and Delta Covid-19 variants, according to a Reuters report.

Shopping malls will be closed and a 9pm to 4am curfew will be imposed from Tuesday onwards in Chonburi, Ayutthaya and Chachoengsao provinces, an announcement on the official Royal Gazette on Sunday showed.

Bangkok and nine other provinces have already been under these restrictions, the toughest in more than a year, since last Monday, as the country battles its longest-running and most severe outbreak so far.
