IDF claims it captured terror operative in Syria

The United Nations Special Coordinator for the Middle East Peace Process Tor Wennesland called the Israeli airstrike in Beit Lahia in northern Gaza "another appalling incident" in a "deadly series of recent mass casualty incidents," in a statement released by the U.N. Secretary-General spokesperson's office Tuesday.

"I unequivocally condemn the widespread killing and injury of civilians in Gaza, and the endless displacement of the population in Gaza," Wennesland said in the statement. "I call on all parties to abide by their obligations under international humanitarian law."

The Biden administration is "deeply troubled" by the Israeli parliament's vote to sharply restrict the U.N. Relief and Works Agency for Palestine Refugees, State Department spokesperson Matt Miller said Tuesday.

"It could shutter UNRWA operations in the West Bank, in Gaza, in East Jerusalem. It poses risks for millions of Palestinians who rely on UNRWA for essential services, including health care and primary and secondary education," Miller said.

"Particularly in Gaza, they play a role right now that, at least today, cannot be filled by anyone else. They are a key partner in delivering food, water and other humanitarian assistance to civilians in Gaza that wouldn't have anyone else to get it from if UNRWA were to go away," Miller said.

Miller said that the U.S. had “made clear our opposition to this bill” to Israeli authorities and said there could be "consequences under U.S. law and U.S. policy for the implementation of this legislation."

"We are going to engage with the government of Israel in the days ahead about how they plan to implement it. We're going to watch and see if there are legal challenges to the law, and if there's any impact by those legal challenges, and then we'll make our decisions after looking to all those facts," Miller said.
