Three metal structures, a van and a car were damaged in a fire that started in one of the 'caravans' in Baħar iċ-Ċagħaq.
Sources said they heard a series of three 'explosions' at a caravan site, but a police spokesperson said these were possibly caused by the fire.
No injuries were reported.
The police were informed of the blast around 1.15pm and by around 2.30pm, the Civil Protection Department had contained the fire.
Investigations to determine the cause of the fire are ongoing.
