CAIRO: The Egyptian president, Abdel Fattah El-Sisi, and his US counterpart, Joe Biden, on Tuesday discussed the efforts being made by Egypt to encourage a ceasefire agreement in Gaza between Israel and Hamas and secure the release of hostages.

Ahmed Fahmy, a spokesperson for the presidency, said the two leaders expressed concern about the potential danger of a threatened Israeli military escalation in the city of Rafah in southern Gaza, which has become the final refuge for more than a million Palestinians displaced by fighting from other parts of the territory. They said it would add a further, catastrophic dimension to the already worsening humanitarian crisis in Gaza, and have wider repercussions on security and stability across the region.

The war began with the Oct. 7 attacks by Hamas on Israel, in which 1,170 people were killed, according to a tally by news agency Agence France-Presse. The militants also took about 250 hostages; Israeli authorities estimate 129 of them are still being held in Gaza, including 34 believed to be dead.

During Biden’s telephone call to El-Sisi, the Egyptian president stressed the need for humanitarian aid workers to be granted full and unrestricted access to Gaza, and highlighted the intensive efforts Egypt has been making in support of the aid effort.

The presidents agreed on the importance of preventing any regional expansion of the conflict, and reaffirmed that a two-state solution to the long-running dispute between Israel and Palestine is the best way to achieve peace, security and stability in the Middle East.

They also highlighted the strategic partnership between Egypt and the US, and their continuing efforts to strengthen bilateral cooperation at all levels.
