Detectives have launched an investigation after a car was rammed into a shop and then set alight.
The attack happened in the early hours of Tuesday morning
The incident happened in the north-eastern part of Glasgow in the early hours of Tuesday morning.
An Asian newsagent's shop in the Riddrie area was left a burned out shell after the attack.
Strathclyde Police confirmed they were investigating the incident but said it was not directly linked to Saturday's airport attack.
Neighbours said the driver sped up to the Smithycroft shop at around 0220 BST and reversed repeatedly to smash through the metal shutters.
Eyewitnesses said the driver then threw a canister into the car, causing an explosion which sparked a major blaze.
The attack followed an incident in West Lothian on Monday where an estate agency next door to a mosque in Bathgate was set on fire.
Police have sealed off the charred building but have yet to establish if either attack was racially motivated.
Residents said they heard a number of loud bangs in the middle of the night.
Margaret Watson, 66, was at home with her grandson, daughter and husband.
She said: "I heard bang, bang, bang; it was like a gun or shooting.
"When I went to look out of the living room window, flames lit up the room, you could feel the heat through the window.
"The car was still there, the driver had reversed in and how they got through the metal shutters I will never know.
"It's quite scary to have something like this happening and if there had been a wind the flames could have spread."
