According to several testimonies, on 4 January Israeli foot soldiers evacuated approximately the people into a single-residence house in Zeitun, half of whom were children, warning them to stay indoors.
But 24-hours later, Israeli forces shelled the home repeatedly, killing between 30 and 60 people.
The UN Office for the Co-ordination of Humanitarian Affairs (OCHA) called it "one of the gravest incidents since the beginning of operations" by Israeli forces in Gaza on December 27.
