Road Transport and Bridges Minister Obaidul Quader on June 17 urged the countrymen to remain alert and united against security threats, reports The Daily Star. “There is no reason to think that the incident that happened in Sri Lanka would not take place in Bangladesh. Incidents like Holey Artisan attack happened in the country. What was the situation in Dhaka after that? The city looked like a ghost town. We all have to remain alert and united,” he said.
