Israel to resume Gaza operation as truce with Hamas crumbles

The Israeli military has told people in Gaza it is resuming operations, saying Hamas broke a planned 72-hour ceasefire just hours after it had begun.

The army said it had warned residents to stay indoors.

Palestinian sources said at least 30 people had been killed in an Israeli attack in Gaza. Israel said it was in response to rocket fire from Hamas.
