Arvind Kejriwal: Containment zones will be increased in Delhi

"Wherever we are finding COVID-19 cases in Delhi, we are declaring those areas as containment zones and conducting 'Operation Shield' there. 33-35 containment zones have been already identified. The number of containment zones will be increased in Delhi in the next 2-3 days. Also, we are starting a sanitisation drive on a large-scale in the red zones or containment zones,": Delhi CM Arvind Kejriwal.
