Rear Admiral Daniel Hagari, an IDF spokesman, responded to reports that there had been intelligence warning about the surprise attack by Hamas on Saturday.
"An intelligence warning of this event - there was not," he said. "We had no understanding of such an event. Certain signs began to appear the night before, but not for something like this, and not enough to be a warning."
"We will fundamentally investigate everything," he promised.
On Wednesday, House Foreign Affairs Chair Michael McCaul (R-TX) spoke to reporters about Hamas' deadly attack on Israel on Saturday and claimed both US and Israeli intelligence operations failed to spot the attack.
"We're not quite sure how we missed it," McCaul said following an all-members classified briefing. "I'm not quite sure how Israel missed it. We know that Egypt had warned the Israelis three days prior that an event like this could happen."
