Patients and staff have been evacuated from Guy’s Hospital in central London following reports of a possible chemical explosion in the building’s basement.

Emergency services, including multiple London Fire Brigade units, ambulances, and police officers, were called to the hospital this morning. Images from the scene show a large cordon in place, patients being assisted by firefighters, and medical staff waiting outside on nearby streets.

A firefighter has been seen helping an elderly woman with a walking stick out of the hospital. Others depict staff and patients gathered in groups while awaiting updates.

Social media users reported hearing about a "chemical explosion" in the basement, though this has not been officially confirmed.  We has contacted hospital representatives for comment.

The incident has prompted a major emergency response around the London Bridge area, with traffic and pedestrian movement restricted as crews continue to assess the situation.

Authorities have not yet confirmed if there are any injuries or the nature of the hazardous material involved.
