Over in China, authorities have recorded the highest number of locally transmitted Covid cases since January, as some cities step up their restrictions, cut commercial travel and boost their testing schemes, APA reports citing BBC.
On 3 August, China reported 71 new locally transmitted cases - the largest since 30 January - although it was not immediately clear how many involved the Delta variant.
The number of cases has increased for the last five consecutive days.
China now has 144 areas deemed to be high or medium-risk - the most since the peak of its epidemic in spring 2020.
Most cities have yet to impose strict citywide lockdowns, but a few have limited some movements, including on planes, buses, trains and taxis.
In Wuhan, where the virus first emerged in late 2019, officials are testing all of the city's 12 million residents after uncovering the first locally transmitted infections since mid-2020.
