Indian doctors said Friday they would increase nationwide protests and strikes after the rape and murder of a colleague, a brutal killing that has focused outrage on the chronic issue of violence against women, reports BSS.

The discovery of the 31-year-old's bloodied and brutalised body on August 9 at a state-run hospital in the eastern city of Kolkata has sparked nationwide protests.

Those in government hospitals across several states on Monday halted elective services "indefinitely" in protest. Multiple medical unions in both government and private systems have backedthe strike.

Thousands marched through the streets of Kolkata overnight Wednesday to condemn the killing, with a candlelight rally at midnight coinciding with the start of India's independence day celebrations.

The Indian Medical Association has called for a "nationwide withdrawal of services" for 24 hours starting Saturday, with suspension of all non-essential and medical procedures at private hospitals.

Indian media have reported that the murdered doctor was found in the teaching hospital's seminar hall, suggesting she had gone there for a brief rest during a long shift.

An autopsy has confirmed sexual assault, and in a petition to the court, the victim's parents have said that they suspected their daughter was gang-raped, according to Indian broadcaster NDTV.
