Japan has extended emergency coronavirus measures in Tokyo and several other regions as the country struggles to rein in the latest wave of infections less than two months before the Olympics.

The state of emergency - the third in the capital since the start of the pandemic - was called in late April and due to end on 11 May but was extended until the end of this month, as restrictions on businesses failed to make a dent in infections.
