Heathrow Airport - the largest in Britain - will remain closed all day today because of a fire at a nearby electrical substation, Reuters reported.
This is expected to seriously affect air traffic. "Heathrow" was the second busiest airport in the world last year after Dubai.
The airport management announced that it would remain closed until 23:59 today (1:59 Bulgarian time tomorrow). People with flights scheduled for today were advised not to go to "Heathrow" at all.
About 150 people were evacuated because of the fire at the electrical substation in Hayes, west London.
