JTA - The family of an Ethiopian-Israeli man held by Hamas in the Gaza Strip after he voluntarily crossed the border fence was given a copy of video footage showing his crossing.

Avraham Abera Mengistu, 30, of Ashkelon, is believed to have voluntarily climbed over the security fence between Israel and Gaza in September 2014, and since then has not been heard from. He suffers from mental illness, according to his family.

Mengistu immigrated with his family to Israel in 1991 when he was 5 years old.

The IDF turned the security video footage over to the family on Saturday night, the Times of Israel reported. The family reportedly saw the footage in the months after Mengistu went missing, but in January requested a copy of it. The handing over of the footage reportedly was approved by Chief of Staff Lt. Gen. Gadi Eisenkot.

Hamas has tacitly admitted through video posted on social media that it holds Mengistu, as well as a Bedouin-Israeli man who also is said to be mentally ill, who crossed into Gaza. Hamas also holds the remains of two Israeli soldiers, Lt. Hadar Goldin and Sgt. Oron Shaul, both killed during Operation Protective Edge in 2014.
