Israeli Prime Minister Benjamin Netanyahu has said he will not send a delegation as planned to Washington after the United States did not veto a UN Security Council proposal calling for a ceasefire in Gaza, Reuters reports.

Netanyahu, according to a statement from his office, said that Washington’s failure to veto the proposal was a “clear retreat” from its previous position, and would hurt efforts against Hamas in Gaza as well as efforts to release over 130 hostages.

“In light of the change in the American position, Prime Minister Netanyahu decided the delegation would not leave,” his office said.
