Updated 11.30pm - Reports of haze across the island
A thick fog descended on Sliema at around 10pm, bringing visibility down to just a few metres.
The haze was so thick that pedestrians on the Strand could barely make out Valletta just across the water.
Readers subsequently reported haze in many other parts of the island, from Mellieha to Attard and Fgura.
These three photos were sent in by Times of Malta readers.
