Met officers say no immediate indication of foul play as passengers face days of disruption from electrical substation blaze

Summary

Counter-terror police are investigating an “unprecedented” fire at an electrical substation near Heathrow Airport, which forced the closure of Europe’s busiest airport, affecting over 1,300 flights and hundreds of thousands of passengers.

The blaze, which broke out Thursday night, damaged the primary and backup transformers. Authorities say there is no indication of foul play but have not ruled out any causes.

Power was restored to most affected areas, but two terminals remain offline.

Disruption is expected for days as airlines scramble to accommodate stranded travelers.
