Israel reopened its only goods crossing with the Gaza Strip on Wednesday after closing it to most deliveries on July 9 over months of border tensions, as relative calm returned and truce talks progressed. An Israeli official said on condition of anonymity that an initial set of “understandings” had been reached with the help of Egypt and United Nations officials, leading to calm over the last several days and the opening of the crossing. Humanitarian issues in the blockaded Gaza Strip and the return of the soldiers can be addressed if calm is maintained, the official said, adding that if not, Israel would return to “aggressive” military action.
