Hundreds of police officers turned their backs on a screen showing New York City Mayor Bill de Blasio as he spoke at the funeral of one of two officers killed last week in what has been called an "assassination."
The funeral at the Christ Tabernacle Church, in the Glendale neighborhood of Queens, was broadcast to thousands of police who gathered outside.
The killing of Officers Rafael Ramos and Wenjian Liu came amid heightened tensions between the police and the mayor over what some police saw as a lack of support for the force.
The atmosphere was mostly respectful, but there were scattered signs of protest even before the police officers action when the mayor spoke.
