Edan Alexander's release prompts hope that this is a "window of opportunity" to secure the release of remaining 58 hostages amid concerns over Israeli military operations.

Hamas released Israeli-American hostage Edan Alexander, who is believed to be the last living U.S. citizen held captive in Gaza. NBC News’ Hala Gorani reports.

CAIRO − Hamas will release the Israeli-American hostage Edan Alexander held in Gaza as a part of efforts to reach a ceasefire agreement and allow humanitarian aid to enter the besieged enclave, a senior Hamas official told Reuters on May 11.

Freeing Alexander, believed to be the last surviving American hostage held by the militant Palestinian group, comes ahead of U.S. President Trump's visit to the Middle East this week.
