At least 100 Jubo League activists, including Awami League (AL) leader Haji Selim, were injured when a procession heading towards Paltan Maidan came under attack by police and BNP cadres in the city's Lalbagh area Tuesday, report agencies.
The activists of Jubo League, the youth front of opposition AL, were marching towards Paltan Maidan to join its grand rally.
Witnesses said the clash ensued when Juba Dal activists accompanied by police tried to resist a procession of several hundred opposition leaders and activists of Lalbagh and Kamrangirchar at Chawkbazar at about 2pm.
As the procession reached the Chawkbazar crossing, police obstructed them putting barricades on the road.
Police opened several rounds of rubber bullet, lobbed tear gas shells and charged batons to disperse the agitated mob when the activists tried to remove the barricades.
In protest against the police action, the opposition activists went on rampage setting fire to three CNG-run auto-rickshaws, two motorbikes, a bus and other vehicles.
Clashes between ruling and opposition activists also took place at different parts in the old town when the activists were coming towards Paltan Maidan to join the grand rally organised by the Jubo League.
Of the injured, 12 were admitted to the Mitford Hospital and eight at the Dhaka Medical College Hospital (DMCH) with bullet wounds.
Of them, condition of Abdur Rahman (35), Babu (22) and Dilu (18) were stated to be critical.
Meanwhile, several other people were injured when Juda Dal cadres attacked opposition activists in Keraniganj.
