The UN human rights office has said it received "disturbing information" alleging the Israeli army summarily executed at least 11 unarmed Palestinians.
The victims, all men, were alleged to have been killed in front of family members in Gaza City's Rimal neighbourhood, with the UN rights office saying it "raises alarm about the possible commission of a war crime".
The Israeli military allegedly surrounded and raided a building in Rimal where four families were sheltering on Tuesday between 20:00 and 23:00 local time (18:00 and 21:00 GMT)
"According to witness accounts circulated by media sources and Euro-Med Human Rights Monitor, while in control of the building and the civilians sheltering there, the IDF [army] allegedly separated the men from the women and children, and then shot and killed at least 11 of the men, mostly aged in their late 20s and early 30s, in front of their family members," the UN rights office said.
