Bangladesh on Friday announced the imposition of a curfew and the deployment of military forces after police failed to quell days of deadly unrest that has spread throughout the country. “The government has decided to impose a curfew and deploy the military in aid of the civilian authorities,” Hasina’s press secretary Nayeemul Islam Khan told AFP. He added that the curfew would take immediate effect. Police in the capital Dhaka earlier took the drastic step of banning all public gatherings for the day — a first since protests began — in an effort to forestall more violence.
