The Gaza ceasefire has been extended for a further 24 hours after the previous ceasefire expired at midnight on Monday.
However, the chief Palestinian delegate to truce talks with Israel warned on Tuesday that Gaza violence could erupt anew unless progress is made toward a lasting deal ahead of a midnight deadline in Egyptian-brokered talks.
After a last-minute agreement was stuck with Israel to extend an expiring truce by 24 hours, Azzam al-Ahmad, senior leader of President Mahmoud Abbas's mainstream Fatah movement, said in Cairo that there had been "no progress on any point" in talks aimed at resolving the Gaza conflict.
"We hope that every minute of the coming 24 hours will be used to reach an agreement, and if not (successful), the circle of violence will continue," Ahmad said.
He accused Israel of "maneuvering and stalling" as gaps on key issues continued to dog efforts to achieve a long-term deal between Israel and militant groups in the Gaza Strip, dominated by Hamas Islamists, which would allow reconstruction aid to flow in after five weeks of fighting.
Senior Hamas official Moussa Abu Marzouk accused Israel of stalling and insisted in a post on his Twitter account that the group "will never cede any" demands for a comprehensive deal.
A senior Palestinian official in Gaza said sticking points to an agreement were Hamas's demands to build a seaport and an airport, which Israel wants to discuss only at a later stage.
Israel, which launched its offensive on July 8 after a surge in Hamas rocket fire across the border, has shown scant interest in making sweeping concessions, and has called for the disarming of militant groups in the enclave of 1.8 million people.
Hamas has said that laying down its weapons is not an option.
