Albanese slams IDF weekend strikes in Gaza
Meanwhile, UN Special Rapporteur Francesca Albanese condemned the IDF's weekend strikes in Gaza in a Sunday post on X/Twitter.
"After killing 500+ people in about 3 months, Israel- armed and supported by the US - continues its genocide in Gaza undisturbed," Albanese's post read. "Don't let it become the new normal. Stand up against genocide!"
According to the IDF, the strikes came in response to ceasefire violations by Hamas and the Palestinian Islamic Jihad on Friday.
The targets of the operation were a weapons storage facility, a weapons manufacturing site, and two launch sites belonging to Hamas in the central Gaza Strip, the IDF said on Saturday.
