JERUSALEM  The Israeli military said Monday that its advocate general had decided to close an investigation into allegations of abuses by soldiers during the recent campaign in Gaza. The allegations arose from the accounts of soldiers at a conference of graduates of a premilitary course at an academic college in northern Israel.

The military police found that “the crucial components of their descriptions were based on hearsay and not supported by specific personal knowledge,” the army said in a statement.

Specifically, a soldier’s claim that orders had been given to fire at an elderly Palestinian woman who entered a no-go zone was found to be based on a rumor, according to the military. Another case, in which a soldier had supposedly been ordered to fire at a woman and two children, was also found not to have been witnessed by the soldier who gave the account.

“After checking the claim, it was found that during this incident a force had opened fire in a different direction, toward two suspicious men who were unrelated to the civilians in question,” the statement said.
