A Fire Department official on Monday said it was fortunate that the damage was minimal from a series of arson attacks across eastern Queens on Sunday night that the police were investigating as a possible bias crime against Muslims.

“It was a good night for the F.D.N.Y. and the people of south Jamaica,” said the official, Lt. Chris Corbin, as he stood outside the scene of one of the attacks, a private home at 146-62 107th Avenue.

No one was hurt in the four attacks, in which homemade firebombs were apparently used. In three of the four attacks, the police said, Molotov cocktails were made with Starbucks bottles.
