The Palestinian militant group Hamas released a video Monday purporting to show a kidnapped Israeli man missing since 2014.
The short clip appears to show Avera Mengistu, who crossed the border into the Hamas-controlled Gaza Strip in 2014 where he was kidnapped by Hamas.
Mengistu has not been heard of since then.
In September, supporters held a rally marking eight years since Mengistu's disappearance.
If authenticated, the video would prove Mengistu is still alive.
"How long will my friends and I remain in captivity here after long years of suffering and pain? Where are the state and the people of Israel?," he appears to say in the video.
Israeli security forces had not verified the video's authenticity by late Monday evening.
