sentences:  On July 4, 1946, the local Jewish gathering of some 200 Holocaust survivors from the Planty 7 Street refugee centre of the Zionist Union became the target of the Kielce pogrom in which 37 (40) Jews (17–21 of whom remain unidentified) and 2 ethnic Poles were killed, including 11 fatally shot with military rifles and 11 more stabbed with bayonets, indicating direct involvement of Polish troops.During the Cold War, many Jewish historians theorized that the pogrom became the cause of outward Jewish emigration from Poland immediately following the opening of the borders in 1947.Nevertheless, the true reasons behind the dramatic increase of Jewish emigration from Poland were far more complex.
