In New York, a gunman opened fire inside a hospital north of Manhattan, killed a doctor and wounded six other people before taking his own life.

The gunman, a former doctor at the hospital, killed himself in the attack.

Mayor Bill de Blasio said the shooting was not an act of terrorism, but rather workplace-related.

He said the attack had been a "horrific situation in the middle of a place that people associate with care and comfort".

Several of the injured are "fighting for their lives," he added.
