ORLANDO (WHDH) – NBC News reports the shooter in the Orlando nightclub massacre called 911 before the attack and swore his allegiance to ISIS.

A SWAT truck and a bomb disposal unit are on the scene of an address associated Omar Mateen.

There is a media staging area set up about a block away from the apartment complex in a residential neighborhood in Fort Pierce, Florida, on Sunday.

Fort Pierce is about 118 miles southeast of Orlando. The apartment complex is a series of two-story buildings.

Numerous police officers and members of the FBI also area there.

Mateen’s father says he’s in shock and that he wasn’t aware of anything his son might have been planning.

Mir Seddique told NBC News that his son got angry when he saw two men kissing in Miami a couple of months ago and thinks that may be related to the shooting.

Seddique says: “We are saying we are apologizing for the whole incident. … We are in shock like the whole country.”

The father also says the incident has nothing to do with religion.

Officials say the shooter was among the 50 killed, and that they’re investigating whether the incident was an act of terrorism.
