The comedy is about a group of British Muslims planning a bomb attack at the London Marathon.
A previous episode of Family Guy was pulled after last December's Sandy Hook school shooting in which 20 children were killed in Newtown, Connecticut.

Later, Peter befriends a terrorist who, unbeknownst to him, is plotting to blow up a bridge. When Peter dials a cellphone the friend has given him, explosions and screams are heard. On some websites, an edited clip has been circulating that fuses the two scenes, making it seem — incorrectly — as if the explosion was at the marathon. Some commenters have implied that the show "predicted" the bombings.
"Family Guy" creator Seth MacFarlane took to Twitter on Tuesday to vent anger over the edited clip and offer condolences to victims of Monday's bombings at the marathon.
"The edited `Family Guy' clip currently circulating is abhorrent," MacFarlane tweeted. "The event was a crime and a tragedy, and my thoughts are with the victims."

The episode contained an unrelated scene in which Peter made friends with a terrorist who was planning to blow up a bridge. This week, edited clips of the episode -- portraying a bombing at the marathon -- began circulating on the Internet. The "Family Guy" episode actually did not feature a bombing at the race. But the out-of-sequence editing made it appear that there was a bombing and mass casualties at the race.
"The edited 'Family Guy' clip currently circulating is abhorrent," MacFarlane wrote on his Twitter account Tuesday. "The event was a crime and a tragedy, and my thoughts are with the victims."
