The Indian Medical Association (IMA) on Friday declared All India Protest Day to express solidarity with striking junior doctors at Nil Ratan Sircar (NRS) Medical College and Hospital in Kolkata over an attack on their colleagues.

Several resident doctors at the AIIMS in Delhi worked with bandages on their heads and wore helmets while treating patients as a symbolic protest and have decided to boycott work.

Junior doctors at the NRS Medical College and Hospital in Kolkata locked up the hospital gates and stopped work at the outpatient department (OPD) on Monday as a mark of protest against the assault on two female and a male intern in the medicine ward of NRS Medical College and Hospital around 5.45 pm the same day.

The protesting doctors refused to call off the strike even after West Bengal Chief Minister Mamata Banerjee reached the state-run SSKM hospital in Kolkata at around noon on Thursday and gave the doctors a four-hour deadline to rejoin service but later revised it to 2 pm.
