Orlando Shooter's Father: Son Mad at Two Men Kissing, 'Nothing to Do With Religion'

The father of suspected Orlando nightclub shooter Omar Mateen said Sunday that the killings that left at least 50 people dead and injured more than 50 others had "nothing to do with religion," but rather that his son was angered after witnessing two men kissing in Miami.

"We are saying we are apologizing for the whole incident," Mir Seddique, Matteen's Afghanistan-born father told NBC News. "We are saying we are apologizing for the whole incident. We weren't aware of any action he is taking. We are in shock like the whole country."

According to law enforcement sources, Mateen was born in New York in 1986 and was living in a Port St. Lucie, Florida home, located about 125 miles south of Orlando. They continued that the shootings, which occurred at Pulse, a large gay nightclub, at about 2 a.m. Sunday are being investigated as an act of terrorism. The death toll marks the largest mass shooting on U.S. soil in recent history.

Also on Sunday, Mustafa Abasin, who answered the phone at Mateen's house when NBC News called, told the reporter that "we are in shock and we are sad." He did not say how he knows the suspect, who police killed at the scene, but told NBC he is helping with the investigation."
