German and Ukrainian police surrounded the ghetto-camp to prevent escape as additional police units entered to round up all the inhabitants. They met with resistance: a barrage of hand grenades and firebombs from buildings, and gunfire from several locations. Nine Germans and Ukrainians were killed, and 20 were wounded. The Germans responded by blowing up or burning the ghetto buildings to kill or flush out their inhabitants. Approximately 3,000 Jews were killed in the ghetto in the course of the Aktion; another 7,000 were captured and sent to the Janowska camp, where they were murdered. The Aktion lasted until June 20, and manhunts in search of hiding Jews continued until July.
