CAIRO, Sept 27 (Aswat Masriya) – Egypt's President Abdel Fattah al-Sisi is scheduled to deliver a speech from Cairo University on Sunday, a source at the presidency said.

The source, who preferred to remain anonymous, told Aswat Masriya that the president's speech will reflect on his visit to the United States last week and his meetings with different world leaders there. Sisi will also honour 20 students from 20 different public universities nationwide.

Republican guards have been securing the vicinity of Cairo University since Friday, the source said. He added that all university students and staff have been given Sunday off. Make-up exams due to begin on Sunday have also been postponed.

Sisi embarked on a trip to the U.S. last Sunday, his first since he was elected president in June. Sisi addressed the General Assembly's 69th session on Wednesday, delivering a speech as Egypt's representative. He also met with U.S. President Barack Obama, when both presidents discussed ongoing regional crises.

Egypt's relations with the U.S. have been tense since the ouster of former Islamist President Mohamed Mursi in July 2013 at the hands of Sisi. 

The U.S. announced temporarily halting part of its 1.3 billion-dollar military aid to Egypt last October pending "credible progress toward an inclusive, democratically elected civilian government through free and fair elections."

In January, the U.S. congress passed a bill resuming the aid in installments and under certain conditions.
