Israeli and Egyptian officials held talks in both countries Sunday aimed at bolstering the Cairo-brokered ceasefire that ended the latest deadly flare-up of violence between the Jewish state and Gaza's Hamas rulers.

Israeli Prime Minister Benjamin Netanyahu met Egyptian intelligence chief Abbas Kamel in Jerusalem to discuss "strengthening cooperation" between their countries, Netanyahu's office said.

Egypt's President Abdel Fattah al-Sisi tasked Kamel and his delegation, who were also to visit the occupied Palestinian Territories, with hammering out a permanent ceasefire deal, senior Egyptian security officials told AFP.

Ashkenazi tweeted on his arrival that they would "discuss establishing a permanent ceasefire with Hamas, a mechanism for providing humanitarian aid and the reconstruction of Gaza with a pivotal role played by the international community".

The Egyptian foreign ministry tweeted that the ministers' talks were "part of Egypt's relentless and continued efforts to revive the peace track and to build on the ceasefire in the Gaza Strip".

Hamas leader Ismail Haniyeh was also expected in Cairo for talks, senior Egyptian security officials said, without providing further details.

Egypt played a pivotal role in negotiating the May 21 ceasefire between Israel and Hamas that brought an end to 11 days of deadly fighting.

Israeli strikes on Gaza killed 254 Palestinians, including 66 children, health officials said.

Rockets and other fire from Gaza claimed 12 lives in Israel, including one child and an Arab-Israeli teenager, medics said.
