PHILADELPHIA – A severed pig’s head was found outside a Philadelphia mosque early Monday, and officials say it may have been thrown from a car window.

The caretaker of the Al Aqsa Islamic Society found the pig’s head near the front door about 6 a.m. early Monday. Surveillance video shows a red pickup truck slowing down in front of the mosque on Sunday night before circling the block. An object can be seen coming from the passenger window.

Pigs are often used to taunt Muslims because the Koran forbids pork consumption.

“It’s worse now than it was after 9/11, which is really frightening,” head of the Philadelphia-based Arab American Development Corp. Marwan Kreidie said, ”[Sept. 11] was a horrible incident, but we didn’t have this kind of reaction, nobody threw a pig’s head. … A pig’s head doesn’t do much. Could the next thing be a pipe bomb?”

“It is a heinous act that sends a message to Arab American communities that they are not wanted here in Philadelphia, and that could not be further from the truth,” Rue Landau, executive director of the Philadelphia Commission on Human Relations, said.

The mosque’s longtime caretaker, Nabil Ibrahim Khalil, said someone left a voice mail message calling Allah “a piece of pork s—” one day after the Paris attacks, according to the paper. The unidentifed caller’s number was handed over to authorities.

Cops are also hoping to be able to enhance the surveillance video to learn more about the truck.

The alarming incident was condemned by Mayor-elect Jim Kenney.

“The bigotry that desecrated Al-Aqsa mosque today has no place in Philadelphia,” he said in a statement. “The City of Brotherly Love and Sisterly Affection has a long history of coming together in the face of challenge.”
