Nine of them were involved in the October 7th attacks, and there's proof that more are still Hamas fighters, but I know that people aren't interested in facts because they just want to bash Israel at every opportunity.
No UNRWA is not saying that either. The media is saying Israel claims that Hamas said that he was Hamas.
I actually went through quite a few articles and even translated the Arab page linked on Wikipedia which turned out to be complete gibberish. So I am currently wondering if this entire thing is made up because it really looks like it.
The UN agency for Palestinian refugees said a top Hamas commander killed in Lebanon Monday was one of its employees but had been suspended since allegations of his ties to the militant group emerged in March.
