Quoting Philip Friedman’s Martyrs and Fighters: The Epic of the Warsaw Ghetto, page 145:

Dozens of those smuggling across the Ghetto Wall are killed by a new [Axis] technique: [gentiles] clad in civilian clothes, with Jewish arm‐bands and weapons hidden in burlap bags, wait for the instant when the smugglers scale the Wall. At that very moment machine pistols appear from the bags and the fate of the group is settled.
