NEW DELHI : The National Democratic Alliance (NDA) government at the Centre on Sunday gave greater powers to state governments to decide on the rules of the lockdown and to classify containment zones, a day before the start of the fourth phase of the lockdown imposed to contain the coronavirus outbreak. “Under the new guidelines, states and Union territories will now delineate red, green and orange zones taking into consideration the parameters shared by the health ministry," said a government release on Sunday evening. “The zones can be a district, or a municipal corporation/municipality or even smaller administrative units such as sub-divisions, as decided by the states and the Union territories," the release added.
