The United States has urged Egypt's new leaders to stop all "politically motivated arrests and detentions".
There was no specific mention of the future of ousted president Mohamed Morsi.
State Department deputy spokeswoman Marie Harf says the continued holding of people in custody is one of the problems Egypt has to resolve on its own if it is to move beyond the political unrest of the past six weeks.
"We continue to call for an end to all politically motivated arrests and detentions and emphasise that this won't help Egypt move beyond the crisis. Our position hasn't changed," Harf said on Monday.
"It's up to the Egyptian people to decide what their government looks like going forward. We've repeatedly made clear that it's not for us to decide."

Islamist leader Morsi has been in detention since his ouster on July 3. When asked about the decision of Egypt's judiciary to extend Morsi's time in custody by 15 days, Harf did not mention the ousted leader by name.
"There needs to be an inclusive, democratic process going forward," Harf said, noting the need for Egyptian leaders to respect people's right to assemble peacefully.
"We don't take sides. We're not going to decide what the future of Egypt's government looks like," she added.
