At least two youths were killed and more than 20 others injured in a clash between two groups over alleged harassment of girls at Abdullahpur village in Debidwar upazila of Cumilla early Thursday. The deceased have been identified as 20-year-old Saiful, son of Habibur Rahman, and 19-year-old Fahim, son of Renu Mia of the same village.  Amir Ullah, assistant superintendent of Brahmanpara circle police, said the clash broke out at the house of a local resident where a ‘haldi ceremony’, a pre-marriage ritual, was organised on Wednesday evening.  "As girls and boys were showing off their dance moves at the programme, a group of youths from the neighbouring Gunjar village in Muradnagar upazila crashed the haldi function and started harassing the girls on the dance floor," the officer said.
