Cadres of the agitating United Democratic Madhesi Front (UDMF) torched the district party office of CPN-UML at Ramgadawa in Birgunj of Parsa on Saturday. The cadres accused the UML of hatching conspiracy to dominate and deprecate the Madhesi agitation. The party had decided to organise a tea reception today. Following the incident, the scheduled programme has been postponed. The Front had on Friday issued a statement and warned the political parties not to organise any activities to foil the ongoing agitation in Tarai.
