The owner of the house that Sinwar got martyred in posted about it.

there was other stories but I won't post them.
translation of what she said:
"Did you know? Yahia Sinwar died fighting, Yahia Sinwar got martyred in Rafah and he got martyred in the home of [family name], we are all pride by Allah" "May our lord replace him with better, and may our lord rest your soul Abu Ibrahim (Sinwar's nickname)"
"By Allah you lit up our home, your sacrifice was truthful.
Our kitchen and its sweet memories"
"Looks like he came to our home because he was destined to martyred in it, May Allah have mercy on him and accept him high up with the rest of the martyrs and we're to Allah and we shall return to him"
