The Israeli military said on Monday that an initial investigation into the killing of 15 emergency workers in south Gaza last month showed that the incident occurred "due to a sense of threat".

JERUSALEM (Reuters) - The Israeli military has provided new details that changed its initial account of the killing of 15 emergency workers near the southern Gaza city of Rafah last month but said investigators were still examining the evidence.

The U.N. has said Israel killed the workers. The video appears to contradict Israel’s version of events, which said the vehicles were “advancing suspiciously” without headlights or emergency signals.
