Prime Minister Sheikh Hasina has called for vigilance to prevent Bangladesh from becoming a haven for anti-liberation forces and sliding backwards.

"We are propelling Bangladesh towards prosperity. This progress must continue. Be vigilant against any forces that may attempt to drag our country backward and transform it into a haven for Razakars [collaborators of Pakistani occupation army]," she said.

Hasina made the call during a reception organised by Bangladeshi expatriates in Germany's Munich on Friday, according to state news agency Bangladesh Sangbad Sangstha.
