- Louisville, Kentucky, is under a state of emergency as prosecutors are expected to announce if police officers who killed a black woman in her home during a drug raid will be charged.
Mayor Greg Fischer said he had declared the measure “due to the potential for civil unrest”.
Breonna Taylor, 26, a hospital emergency room technician, was shot multiple times on 13 March.
Her name has become a rallying cry for anti-police brutality protesters.
Kentucky Attorney General Daniel Cameron is expected to announce any day whether his office will bring charges.
How is the city preparing?
Mayor Fischer’s emergency declaration on Tuesday noted that protests have been held for over 100 consecutive days in Louisville.
The city leader, a Democrat, is authorising police to close traffic on certain streets where protests have been prevalent.
