Israel has pushed back on the claim, with Prime Minister Benjamin Netanyahu dismissing as “fake news” the reports that the country received any sort of warning.
But McCaul, speaking after a closed-door briefing, said lawmakers had heard from the Biden administration, which is working with Israeli officials to help manage the ongoing crisis.
“There seems to have been a failure of intelligence,” McCaul said. “We’re not quite sure how we missed it. We’re 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.”
He added that the attack “had been planned perhaps as long as a year ago.”
Lawmakers are also concerned about an “escalation” in the crisis that could potentially draw in militant responses from Lebanon, Iran and elsewhere.
“We know that Hezbollah has 100,000 rockets that would overwhelm the Iron Dome,” McCaul said, referring to the Lebanese militant group and Israel’s high-tech anti-missile defense system.
However, Egyptian officials have reportedly rejected the idea of setting up safe corridors for civilians to flee into Egypt. Reuters reported that officials are instead discussing how to allow humanitarian resources to flow through the Rafah Crossing.
