No terrorism connection in deadly crash

US President Barack Obama has been briefed on the plane crash in the French Alps that killed 150 people, with the White House saying there don't appear to be any terrorist links.

Obama's assistant for homeland security and counterterrorism Lisa Monaco appraised the president about the Germanwings Airbus 320 crash.

"There is no indication of a nexus to terrorism at this time," National Security Council spokesperson Bernadette Meehan said of Tuesday's crash.

"US officials have been in touch with French, German, and Spanish authorities and have offered assistance.

"Our thoughts and prayers are with the victims and their families and loved ones."
