US heatwave claims 30 lives

Americans dipped into the water, went to the cinema and took tube trains just to have air conditioning relief from unrelenting heat that has killed at least 30 people across half the country.

The heat sent temperatures soaring over 100 degrees Fahrenheit (38 degrees Celsius) in several cities, including a record 105 F (40.5 C) in Washington, St Louis (106 F, 41 C), and Indianapolis (104 F, 40 C), buckled highways and derailed a Washington-area train even as another round of summer storms threatened.
