DHAKA: Fear has gripped Bangladesh’s tiny Christian minority after three crude bomb attacks on churches and a Catholic school, which police on Sunday said caused no injuries but were “certainly” designed to sow terror.No group has claimed responsibility for the incidents or explained why the Christian community, which numbers around 500,000 people of the South Asian nation’s 170 million citizens, was targeted.“We are trying to determine whether the incidents are connected or isolated — they are certainly aimed at terrifying people,” Dhaka police spokesman Muhammad Talebur Rahman told AFP.Bangl
