Syed Rizwan Farook Pakistan

Pakistan remains a "safe haven" for terrorists and a source of "radical Islamist thought" while its security agencies support terrorist groups destabilising Afghanistan and threatening India, a top US lawmaker said on Wednesday.

Investigators believe San Bernardino shooter Syed Farook may have been plotting an earlier attack in California with someone else, CNN reported on Tuesday, citing two US officials.

The Pakistani woman suspect in the California mass shooting may have travelled to India from Saudi Arabia once in 2013, a year before she went to the United States with her husband, a media report said today.

Two weeks before he and his Pakistani wife went on to kill 14 people in California, a USD 28,500 deposit was made to the account of slain gunman Syed Farook, a media report has said.

Investigations into the San Bernardino shooting carried out by a radicalised couple has expanded overseas including Pakistan, a top US official has said.

Soon after the deadly shooting in California, a flurry of tweets by supporters of ISIS boasted of the terror group's connections to the attack in which 14 people were killed and 21 others injured.

The deadly California shooting that killed 14 and injured 17 was a terrorist attack conducted by perpetrators inspired by ISIS and possibly linked to Al-Qaeda, according to a top American think tank known for its expertise on terrorists organisations.
