Israel has withdrawn its negotiating team from Qatar, terminating immediate attempts to reach a ceasefire and hostage release deal with Hamas. The action comes in the aftermath of a UN security council vote demanding a truce and Hamas rejecting the latest proposals.

Israeli prime minister Benjamin Netanyahu’s office said in a statement that “Israel will not cave to Hamas’s delusional demands.”

It said the Hamas attitude was “clear proof it is not interested in continuing talks and a sad testament to the damage caused by the UN Security Council resolution.”

Late on Monday evening, Hamas issued a statement rejecting the new peace offer, saying Israel was not responding to its key demands of a “comprehensive ceasefire, a withdrawal from the Strip, the return of displaced people, and a real prisoner exchange.”

Earlier on Tuesday, Israel’s foreign minister, Israel Katz, said Hamas had been encouraged to reject a deal by the vote for a truce at the UN security council and had been sent the message “you don’t have to hurry” since international pressure was being bought to bear on Israel.

The UN Security Council resolution that passed on Monday demanded an immediate ceasefire for the month of Ramadan and also demanded the release of hostages by Hamas. It was the first time a resolution about an Israel-Gaza war ceasefire avoided being vetoed by one of the US, China, or Russia. After the UN vote, Benjamin Netanyahu’s administration postponed a planned visit to Washington by two of his ministers.

A persistent sticking point in ceasefire negotiations is alleged to be a Hamas demand that Israel withdraw from Gaza militarily during the ceasefire.

The Times of Israel said that an Israeli insider informed it, “There is no one to talk to on the other side, and the Israeli negotiating team has nothing to do in Qatar.”
