The United Nations High Commissioner for Human Rights, Volker Türk, warned on Tuesday that the situation in the West Bank, including East Jerusalem, was “deteriorating significantly.”

He added, according to Reuters, that there is “death and suffering that cannot be accepted by conscience” in Gaza.

He noted that as of June 15, 528 Palestinians, including 133 children, had been killed by Israeli security forces or settlers since October, and said some cases raised “serious concerns about unlawful killings.”
