Heathrow Airport terminal in London resumes operations following hazardous substance incident

In an unexpected turn of events, Heathrow Airport's Terminal 4 was evacuated earlier today due to a "possible hazardous materials incident." The airport has since declared the terminal safe and reopened it after the incident.

According to reports, paramedics treated 21 patients at the terminal, and one patient was taken to a hospital. Unverified video clips showed dozens of passengers waiting outside the terminal. The London Fire Brigade has stood down its response to the incident. However, no information about the nature of the incident has been disclosed.

The London Metropolitan Police conducted a thorough search at Heathrow Airport's Terminal 4, but no trace of any "adverse substance" was found. The airport has apologised for the disruption caused and stated they are working to ensure all flights depart as planned. Flights are still taking off at Heathrow Airport despite the incident at Terminal 4.

In other news, the departures section on Heathrow's website showed flights continuing to take off. The entire airport was not shut down this time, unlike the incident in March when a huge fire at a nearby electrical substation caused a shutdown.

Meanwhile, in Dubai, gold prices have slipped from their all-time high. 22K gold dipped below Dh400 per gram. This drop comes as investors are pushing gold prices towards $5,000 amid ongoing instability.

In a separate development, a warning has been issued stating that 70% of smart home devices in the UAE are vulnerable to cyberattacks. Specialist officers from London's Metropolitan Police conducted a search at Heathrow Airport's Terminal 4, but no information about their mission was disclosed.

Lastly, same-day delivery has become the new standard in the UAE retail sector. With the increasing demand for quick and efficient services, this trend is expected to continue.
