Hamas leader Ismail Haniya said today that Israel’s military actions in Gaza could bring talks on a ceasefire back to square one, the Palestinian Islamist movement said on Telegram.

In a phone call with mediators to reach a truce deal, Haniya said he considered Israeli Prime Minister Benjamin Netanyahu and Israel fully responsible for the possible collapse of the negotiations, Hamas said.

Earlier today, Hamas accused him Netanyahu that it stands in the way of negotiations for a cease-fire in the Gaza Strip amid ongoing talks aimed at reaching an agreement to end the war.

The Palestinian Islamist movement, in a statement, called on mediators to intervene against what it called Netanyahu’s “maneuvers and crimes.”

The Israeli prime minister said yesterday that any agreement on a ceasefire in Gauze it must allow Israel to continue fighting until its goals are achieved.

Today, Israeli tanks advanced into central Gaza City after a night of shelling that Gaza authorities said had killed dozens of people, even as negotiations on a ceasefire deal intensified.

“While the Hamas movement is showing flexibility and a positive attitude to facilitate an agreement to end the Zionist aggression, Netanyahu is raising additional obstacles in the way of negotiations as he escalates his aggression and crimes against our people“, the Palestinian Islamist movement reported. Hamas on Saturday accepted a key part of a US plan aimed at ending the nine-month war in Gaza, rejecting an Israeli demand that it first commit to a permanent ceasefire before signing the deal.

A US delegation headed by CIA Director William Burns arrived today at Cairo to meet with an Egyptian security delegation in a new round of ceasefire talks, the Egyptian state-linked Al Qahera News reported.
