CPI(M) general secretary Sitaram Yechury Friday accused West Bengal Chief Minister Mamata Banerjee of politicising the issue of doctors' agitation and the Bharatiya Janata Party (BJP) of communalising it.

Protesting doctors demanded Banerjee's unconditional apology and set six conditions for the state government to withdraw their four-day-long stir that disrupted healthcare services across West Bengal.

"West Bengal govt must invite health workers & resolve this humanitarian crisis on a war footing. CM is trying to politicise instead of discharging basic responsibility. BJP wants to communalise by highlighting the religious identity of victims of a tragedy," he tweeted.

While visiting the SSKM Hospital on Thursday, Banerjee had contended that "outsiders" had entered medical colleges to create disturbances and the agitation was a conspiracy by the CPI(M) and the BJP.

Listing the six conditions, the agitators said the chief minister will have to visit the injured doctors at the hospital and her office should release a statement condemning the attack on them.
