MOSCOW (Sputnik) – Two other federal law enforcement officials told the newspaper on Friday that Malik also pledged allegiance to a leader of the Islamic State (Daesh) terrorist group, also known as Daesh, which is outlawed in a range of countries including Russia.
Comey added, however, that it was not clear whether the San Bernardino shooters were part of a terrorist organization or network.
"We have no indication that these killers are part of an organized larger group or form part of a cell. There is no indication that they are part of a network," the FBI Director said.
FBI Los Angeles Assistant Director David Bowdich said on Friday that the San Bernardino shooting was being probed as an act of terrorism, but could not confirm that the California gunmen were influence by the Daesh.
On Wednesday, a shooting at Inland Regional Center in San Bernardino, California (about 60 miles east of Los Angeles) took the lives of 14 people, injuring over 20 others.
Police identified the shooters as a US-born man of Pakistani origin Syed Rizwan Farook and his wife Tashfeen Malik, a Pakistani national who was in the United States on a K1 (fiancée) visa. The couple was killed in a shootout with police hours after the Wednesday attack.
