The British embassy in Cairo suspended public services on Sunday for security reasons, an embassy spokesperson said.
The embassy declined to give more details due to the sensitive nature of the matter but one official said efforts were under way to make sure it could reopen “safely”. It was not clear when the facility would reopen.
The British embassy website said the office of the British Consulate-General in Alexandria was operating as normal.
Days earlier, the US embassy had released a statement warning staff not to stray too far from their homes.
