Twelve-year-old boy killed and 100 wounded in attack on procession of Shia Muslims marking holy day of Ashoura in Dhaka, the Associated Press news agency said with the reference to local police.
Police cordoned off the area early Oct.24 and were investigating the blasts, which they said were caused by improvised explosive devices. They said it was unclear who carried out the attack.
Local police chief Aziz Ahmed said a 12-year-old boy died as three handmade grenades blasted, while the injured were being treated.
Witnesses said that people ran frantically after blasts, losing their flip-flops and sandals as they scattered.
At least 10 people were admitted to Dhaka Medical College Hospital, and most of them were in a stable condition, according to Nazimunnesa, a deputy director.
Attacks on the Shia minority have been rare in Sunni majority Bangladesh.
Nobody has claimed the responsibility for the attack.
Ashura, or the 10th of Muharram in the Islamic calendar, is observed in Bangladesh to commemorate the martyrdom of Imam Hussain, grandson of Islam's Prophet Mohammed.
