Here he is:
He comes from a proud family of Qassam Brigade "martyrs." The Ghalban family has a Facebook page where they celebrate all of them.
PCHR did identify Mohammed Khamis al-Ghalban and Ahmed Hassan Saleh al-Ghalban as members of armed groups. I could not find any mention of Bilal or Mohammed Fathi Ghalban, also listed there as Al Qassam martyrs. It is interesting that of this terrorist family, PCHR still identified Ayman as a "civilian." (UPDATE: Mohammed Fathi was listed as a member of an armed group in PCHR, h/t Bob Knot)
Also the family has a photo of another of their members who was injured, Mohamed Raafat Ghalban, who is almost certainly a terrorist himself, being treated at a Turkish hospital and being visited by Turkish president Erdogan.
In other news, Ma'an reports:
A young Palestinian man died on Monday of wounds he sustained during the Israeli offensive on Gaza, a Ma'an reporter said.What Ma'an didn't mention is that he was a terrorist in the Al Quds Brigades.
Muhammad Ibrahim al-Riyati, 22, was critically injured on July 18 when Israeli forces shelled the al-Tanur neighborhood of Rafah in the southern Gaza Strip.
Al-Riyati was taken to an Egyptian hospital, where he was pronounced dead on Monday.
Just an oversight, no doubt.
