This handout picture provided by the Hostages and Missing Families Forum Headquarters shows an image grab from a video released by Hamas's armed wing Ezzedine al-Qassam Brigades, of Israeli hostage Edan Alexander, held in the Gaza Strip since October 2023. AFP
The Ezzedine al-Qassam Brigades published the more than three-minute clip showing the captive seated in a small, enclosed space.
AFP was unable to immediately verify the authenticity of the footage or determine when it was filmed.
In the video, the captive says he wants to return home to celebrate the holidays.
Israel is currently marking Passover, a holiday that commemorates the biblical liberation of the Israelites from slavery in Egypt.
The captive appears to be speaking under duress in the video, making frequent hand gestures as he criticises Prime Minister Benjamin Netanyahu's government for failing to secure his release.
The video was released hours after Defence Minister Israel Katz announced that Israel's military had seized the new Morag axis between the southern cities of Rafah and Khan Yunis.
Katz also outlined plans to expand the military's ongoing offensive across much of the Gaza Strip.
In a separate statement earlier Saturday, Hamas said Israel's Gaza operations endangered not only Palestinian civilians but also the remaining captives.
The brutal offensive not only "kills defenceless civilians but also makes the fate of the occupation's prisoners (hostages) uncertain", Hamas said.
On October 7, 2023, Palestinian militants took 251 captives.
Fifty-eight captives remain in captivity, including 34 whom the Israeli military says are dead.
During a recent ceasefire that ended on March 18 when Israel resumed air strikes on Gaza, militants released 33 captives, among them eight bodies.
