(Reuters) The estranged relatives of Tashfeen Malik, a Pakistani woman accused of shooting dead 14 people in California, say she and her father seem to have abandoned the family's moderate Islam and became more radicalised during years they spent in Saudi Arabia.
Malik, with her husband Syed Rizwan Farook, 28, is accused of storming a gathering in San Bernardino, California, on Wednesday and opening fire in America's worst mass shooting in three years.
Investigators are treating Wednesday's attack as an "act of terrorism." On Saturday, the Islamic State (IS) group claimed the couple as their followers. There is no evidence yet that IS directed the attack or even knew the attackers.
