DHAKA     -   Hundreds of students protested across Bangladesh on Wednesday calling for political groups to be banned from campuses days after a student was killed, allegedly by activists from Prime Minister Sheikh Hasina’s ruling party. The protests started in Dhaka after Sunday’s killing of 21-year-old Abrar Fahad at the dormitory of the Bangladesh University of Engineering and Technology (BUET), where he was a second-year student. He had written a Facebook post criticising a government water deal with India. Responding to the protests, Hasina said the government would not interfere if any university decided to ban political groups. She said she had ordered her party’s student wing to expel anyone involved in the “extremely cruel” killing. “I can feel the pain of the parents who lost their child,” Hasina told a news conference at her official residence. Protests spread across the country on Wednesday, with many teachers joining students, who chanted slogans demanding justice. Police said they had arrested 13 leaders of the Chhatra League - the student wing of Hasina’s Bangladesh Awami League - whose members have been accused of beating and killing Fahad by his fellow students and family. “My son was innocent. He had his own opinions,” said Barkat Ullah, Fahad’s father.
