The office of Egypt's last major independent media outlet has been raided by plainclothes security officers, its editors say.
On Facebook, Mada Masr said laptops and phones were confiscated and three staff members briefly arrested.
Despite being blocked in Egypt since 2017, the website is accessible in the country via virtual private networks.
The authorities have not commented. There has been a crackdown on dissent and free speech under President Sisi.
