The protesting farmer unions will not be blocked of roads and national highways in Delhi, Uttarakhand and Uttar Pradesh on Saturday during the nationwide chakka jam by the protesters. "There will be no chakka jam programme inside Delhi since all the protest sites are already in a chakka jam mode. All roads for entering into Delhi will remain open except where farmers' protest sites are already located," a farmer union said in a statement. The farmer unions have also asked the protesters to be peaceful during the chakka jam. Meanwhile, the Delhi Police has taken additional measures this time, including tightening security and intensifying vigil at the city's border points, to deal with any situation emerging out of the 'chakka jam'.
