WASHINGTON (Sputnik) — On June 12, 29-year-old Mateen opened fire in The Pulse, a gay nightclub in Orlando, Florida, killing 49 people and injuring 53 others. The FBI confirmed on Wednesday that the attack is being investigated as an act of terror.
"We have not been able to uncover any direct link between that individual Mateen and a foreign terrorist organization," Brennan said during a Senate hearing.
The shooter’s father, Seddique Mateen, said his son did not have ties to Daesh terrorist group, banned in a range of countries worldwide, according to CNN.
Mateen’s attack is the deadliest mass shooting in the history of the United States.
