From The New York Times:
Protesters across Russia took to the streets to show their disapproval of the “partial mobilization” policy announced by President Vladimir V. Putin on Wednesday morning that would press 300,000 into military service. At least 1,252 people from 38 cities were detained, according to OVD-Info, a human rights watchdog that monitors police activity.
In Moscow, hundreds of protesters gathered on the Old Arbat, a well-known pedestrian street in central Moscow. They screamed “Send Putin to the trenches!” and “Let our children live!” Footage showed riot police dragging people away.
