A Gaza Palestinian border official said Egypt has closed its border with the Hamas-ruled territory amid the raging turmoil in Egypt.
Ghazi Hamad said he expected the closure to last several days.
The border terminal at Rafah had been rescheduled to open Sunday after a routine, two-day weekend closure. About 400 to 600 Palestinians cross through the terminal daily for medical treatment, study and family visits.
Gaza reports also said three Palestinians who were imprisoned in Egypt had escaped during the upheaval and had returned to the coastal territory through smuggling tunnels.
Hamas officials said group leaders have postponed a trip through Egypt to Syria, where they were to discuss a new proposal to free a long-held Israeli soldier.
