Senior Hamas official Basem Naim told Al Jazeera that Israel is not meeting the terms of the ceasefire agreement before the group called for an indefinite delay in the release of Israeli captives.

“In the last three weeks after signing the deal we have been in very serious talks and negotiations with the mediators — the Egyptians, the Qataris, and the United States — about the daily violations by the Israelis of the deal,” Naim said.

He noted that 25 Palestinians had been killed and dozens wounded by Israeli forces after the ceasefire went into effect.

Hamas officials called for hundreds of thousands of tents to be brought into Gaza to shelter people amid freezing conditions, and the necessary aid has not arrived.

“We are lacking any sources of electricity, we have called for generators to enter the strip,” Naim said.

“We have told them clearly how can we continue the prisoner exchange, including the dead bodies of the captured Israelis, if until now we don’t have any heavy machinery.

“We are committed to the ceasefire agreement, we have done our part. We have fulfilled all our obligations and we are still committed and we are working to avoid any obstacles and overcome any challenges. The Israelis are intentionally sabotaging the deal and undermining the agreement.”
