In December, Israeli ground troops entered a Gaza apartment building filled with innocent people. Survivors told Al Jazeera that the soldiers left a “bloodbath” in their wake.

Working with journalists in Gaza, Al Jazeera English investigated a number of Israeli military attacks as part of The Night Won’t End, a documentary we reported and produced for the show Fault Lines and which was released last Friday. While we reported on incidents ranging from a massive air strike to attacks on safe zones to the killing of 6-year-old Hind Rajab, we also sought to focus on an issue that has received more limited media coverage: allegations of arbitrary executions of civilians by Israeli ground forces.

This is the story of one of those alleged incidents. We verified the details of the attack using the testimony of six survivors, satellite imagery, phone messages, and video footage.
