Calcutta, Dec. 6 :    Calcutta, Dec. 6:  Traffic in central and north Calcutta was crippled for hours on Wednesday afternoon after several political parties, students and youth organisations took out rallies condemning the demolition of Babri Masjid in 1992. Traffic on College Street, Nirmal Chandra Chunder Street, Lenin Sarani, Jawaharlal Nehru Road, Rani Rashmoni Road, S.N. Banerjee Road and a part of AJC Bose Road came to a standstill after 3 pm, as most of the rallies followed almost the same route and ended at Rani Rashmoni Road around 4.30 pm. A large contingent of police was deployed in the area to control the traffic. No untoward incidents were reported. The youth and students' wings of the CPM -the DYFI and SFI - took out a procession from Raja Subodh Mullick Square, passing through Lenin Sarani and Jawahar Lal Nehru Road and terminating at Rani Rashmoni Road. The West Bengal Youth Congress' rally started from College Square and passed through College Street, Nirmal Chandra Chunder Street, Lenin Sarani and Jawahar Lal Nehru Road, before ending at Rani Rashmoni Road. Among the non-political organisations was the Muslim-Urdu Coordination Committee, which started its procession opposite Metro cinema. The police cut short the rally at Rani Rashmoni Road. The Bangiya Christiya Parishad started from Moulali and ended at Rani Rashmoni Road too. About 500 supporters of the Samajwadi Party assembled at the base of the Gandhi statue on the Maidan. Almost the same number of Rashtriya Janata Dal supporters also met at Shahid Minar.
