Rizwan Farook and Tashfeen Malik

The FBI has unlocked the iPhone used by one of the San Bernardino attackers, officials said March 28, ending a heated legal standoff with Apple that had pitted US authorities against Silicon Valley.

A court order the U.S. government requested to force Apple to unlock an iPhone linked to the San Bernardino shooting rampage is about "the victims and justice," FBI Director James Comey said.

Apple Inc Chief Executive Tim Cook said his company opposed a demand from a U.S. judge to help the FBI break into an iPhone recovered from one of the San Bernardino shooters.

Cook said that the demand threatened the security of Apple's customers and had "implications far beyond the legal case at hand." 

Islamic State of Iraq and the Levant (ISIL) said on Dec. 4 that the married couple who killed 14 people in a mass shooting in Southern California were its followers, and FBI agents raided a home apparently belonging to a friend of the husband. 

Islamic State (IS) militants claimed responsibility for the shooting in San Bernardino in southern California on Wednesday, which claimed the lives of fourteen people and left 21 injured.

Militants of IS described the two perpetrators, who stormed a Christmas party at the county department of public health as "supporters" of the terrorist group.

Tashfeen Malik, the female suspect in the California mass shooting, had pledged allegiance to the leader of the Islamic State group on Facebook, according to US officials.

The post was made under an account with a different name.

ISIS extremists started celebrating the shooting in San Bernardino, where 14 people died and 17 were wounded, creating the hashtag #America_Burning.

The Islamic State, however, has not yet taken credit for the shootings in the postings.

Police on Dec. 2 identified the two suspects, a man and a woman, who died in an exchange of fire with police following the mass shooting that killed 14 people in California.
 

As many as three people killed at least 14 people and wounded another 17 during a Christmas party at a center for the disabled in San Bernardino, California, on Wednesday. Three shooters, reportedly clad in military-style gear and masks, barged into the center and opened fired in the deadliest mass shooting to take place in the United States in three years.
