Japan widens emergency over 'frightening' Covid spike

Japan is extending a state of emergency in Tokyo and expanding it to new regions as the Olympic host faces a surge in Covid cases.

The restrictions are being imposed in areas surrounding the capital as well as in the city of Osaka.

Japan's PM Yoshihide Suga warned infections were spreading at an unprecedented rate, urging the country to watch the Games from home.

New cases are being fuelled by the more infectious Delta variant.
