The Israeli military on Wednesday said that a February strike on Khan Younis in southern Gaza may have led Hamas militants to execute six hostages.

The Israeli military shed light Wednesday on the circumstances surrounding the deaths early this year of six male hostages who were found shot in a Gaza tunnel—and whose captors were also found dead at their side.

The six hostages, whose bodies were found in Gaza over the summer, were probably shot in February by their captors as an Israeli strike hit close to the tunnel where they were held, the military said.
