Britain’s Heathrow Airport said on Friday that it had begun reopening after a massive fire at a nearby electrical substation knocked out power, forcing a shutdown at Europe’s busiest airport and disrupting the flight schedules of airlines globally.

At least 120 inbound flights to Heathrow were diverted to other airports, according to flight-tracking website FlightRadar24.
