WASHINGTON (REUTERS) - A Facebook profile established under an alias by Tashfeen Malik, one of the suspects in the California shooting, was removed by the company for violating its community standards, which prohibit praise or promotion of "acts of terror," a spokesman said Friday.

Content celebrating leaders of the Islamic State in Iraq and Syria (ISIS) would be removed under the company's standards, said a Facebook spokesman, who asked not to be named.

He did not directly say the ISIS comments were what triggered the removal on Thursday.

He added that Facebook is cooperating with law enforcement on the matter.

Law enforcement sources have said that material on the Facebook page included praise of the ISIS.

It was unclear how Facebook discovered the account and how the company linked it to Malik.
