WASHINGTON, Nov. 24 (Xinhua) -- U.S. President Donald Trump Friday spoke with Egyptian and Turkish presidents over phone about Friday's deadly mosque attack in Egypt and the Syrian issue.

In his conversation with Egyptian President Abdel Fattah al-Sisi, Trump offered condolences to the people of Egypt after the "heinous" attack on worshippers in Egypt's North Sinai province, according to a readout released by the White House.

Reiterating that the United States will continue to stand with Egypt in the face of terrorism, Trump noted that the international community must strengthen its efforts to defeat terrorism and extremism in all forms.

The attack, which took place at the mosque in a small village in North Sinai, at least killed 235 worshippers and wounded 109 others.

Earlier, Trump talked with his Turkish counterpart Recep Tayyip Erdogan about Syria. They discussed the importance of implementing UN Security Council Resolution 2254 and supporting the UN-led Geneva process to peacefully resolve the conflict in Syria.

Underscoring the need to end Syria's humanitarian crisis and to allow displaced Syrians to return home, Trump and Erdogan said efforts shall be made to "ensure the stability of a unified Syria free of malign intervention and terrorist safe havens."

Trump also informed Erdogan of pending adjustments to the military support on the ground in Syria, saying the battle of Raqqa is considered complete and the situation "is progressing into a stabilization phase" to ensure that the Islamic States cannot return to Syria.

The two leaders also discussed the Turkish purchase of military equipment from the United States.
