A gunman has shot dead two police officers sitting inside a patrol car in New York before killing himself.
The head of the New York police said the men had been “targeted for their uniform”. The gunman then ran into a subway station where he shot himself, the BBC reported.
Earlier he had posted anti-police messages on social media.
President Barack Obama - who is on holiday in Hawaii - said he condemned the killings unconditionally.
The mayor of New York, Bill de Blasio, said anyone who saw postings indicating a threat to the police should report them to the authorities. The “whole city was in mourning” after the shootings, he said.
The shootings come at a time when New York City police are facing intense scrutiny for their tactics, according to the BBC.
Earlier this month, a grand jury did not indict any New York police department officer in the chokehold death of Eric Garner, a black man who died when white police officers tried to arrest him for selling cigarettes.
The decision sparked protests in New York and other cities across the US.
