The fire alarm in London's Houses of Parliament went off earlier today, as steam – initially mistaken for smoke – bellowed from the building's roof.
Jessica Gallardo filmed the incident and shared the video on Twitter.
Later, she added that she had not seen a fire.
The UK government later confirmed that it was "just steam," as quoted by The Daily Express. However, lawmakers have not explained why the fire alarm sounded.
The Restoration and Renewal Sponsor Body has repeatedly warned that the Houses of Parliament need major repairs, with over 40,000 problems reported in the past three years, the paper added.
