Heathrow Terminal Is Safe to Reopen After Earlier Evacuation

London Heathrow Airport’s Terminal 4 is safe to reopen after being evacuated earlier on Monday for what emergency responders said was a possible hazardous materials incident.

Emergency services confirmed the facility could resume operations, a spokesperson for the airport said in a statement, without detailing the earlier incident and what prompted the all-clear. Earlier on Monday, the airport had briefly closed Terminal 4’s check-in area as firefighters responded.
