Large swathes of the Russian capital are still without electricity after an explosion at a substation overnight. The stock exchange was closed for two hours, Moscow’s transport network has all but shut down and mobile phone services may be disrupted. The underground came to a halt, leaving 20,000 passengers stranded in tunnels in sweltering temperatures. Trams and trolleybuses ground to a standstill and traffic lights stopped working, causing several accidents.
Water supplies to people’s homes are also affected. Russia’s energy minister said the substation blast was caused by a technical fault.
