Israel-Gaza live updates: Gaza without power as death toll continues to mount

Two U.S. officials familiar with the diplomatic efforts to free hostages told ABC News it appears that allies and partners in the Middle East in communication with Hamas are being helpful in advocating for their release.

The officials say Hamas has shown no real willingness to partake in diplomacy up to this point.

Hamas’ designation as a foreign terrorist organization also complicates any negotiations involving the U.S., because the official label makes it illegal for any American to knowingly provide “material support or resources,” which includes personnel.

Deputy Special Envoy for Hostage Affairs Steve Gillen is among the U.S. delegation en route to Israel with the Secretary of State Antony Blinken.

In remarks earlier Wednesday, President Joe Biden said “there’s a lot we’re doing” to bring the hostages home.

“In the days ahead we’re gonna continue to work closely with our partners in Israel and around the world,” he said.
