Patients in the East of England have been encouraged to attend their appointments as resident doctors' strikes continue.
Industrial action over pay will continue until 07:00 BST on Wednesday 30 July, but patients should still attend their appointments unless contacted to reschedule, said NHS England.
Adam Cayley, the chief operating officer for NHS England in the East, thanked staff for their "hard work over the weekend" and "continued efforts in the days ahead".
The latest series of strikes began on Friday and patients who need emergency medical care have been told to use 999 or go to A&E as normal.
