Two people were hurt leaping from a first floor window when a fire ripped through flats and businesses in Birmingham on Christmas Day.
Eleven others were evacuated from the buildings after the fire started in a shisha lounge in High Street, Deritend, Digbeth at 03.15 GMT.
The two that jumped to safety suffered broken bones.
Firefighter Dave Burton said the suspected cause of the blaze was arson. Investigations are ongoing.
He was unable to reveal how many buildings were involved in total.
Crews left the scene just before 20:00 on Christmas Day.
