The youngest victim of the October 7 massacre was just 14 hours old, a UK parliamentary report has found.

The study also disclosed the existence of another Briton who died in the attack, bringing the total number of UK citizens killed to 18.

Lord Roberts, the historian who has presided over the report, said its purpose was to produce a definitive account of the Hamas attacks to “counter pernicious” attempts at denying or minimising the atrocities.

The report’s main findings – corroborating studies that have come out of Israel – found that planning by Hamas had begun in 2018, five years before the massacre; and that 7,000 militants had taken part in a “co-ordinated assault” launched from Gaza on 55 separate locations in Israel.
