Two Las Vegas shootings, one officer shot amid Floyd protests

A Las Vegas police officer was shot Monday night amid protests over the killing of George Floyd, local media said.

The officer was shot in the area of the Las Vegas Strip and another officer was "involved in a shooting" in the same area, reported AP, without giving details of the officers' condition.

So far, at least five U.S. police have been hit by gunfire during protests, and U.S. President Donald Trump has vowed to use the military to stem the unrest.
