The terrorists were believed to be hiding in the school."They threw a bomb at a police checkpost. A constable was killed in the explosion. One attacker was killed and another was arrested," Mahbubur Rahman, a police officer in the district control room, was reported as saying by news agency AFP.Tofazzal Hosain, the district's deputy police chief, told AFP that several people had taken part in the attack and some had been armed with machetes - a hallmark of recent attacks in Bangladesh."They first threw a small bomb targeting police and then attacked them with machetes. Police retaliated by returning gunfire," Mr Hosain said.Some reports suggest that the attack was targeted at the imam or chief cleric of Kishoreganj, who is known for his liberal views. He had reportedly started a signature campaign to condemn terrorism in the name of Islam.'How can people attack those who have been doing namaz?' asked Prime Minister Sheikh Hasina.Last weekend, 20 people, including 18 foreigners, were hacked to death at the Dhaka cafe.Bangladesh has faced a growing wave of attacks since the turn of the year, many of which have been claimed by the ISIS or an offshoot of the Al Qaeda network.Yesterday, the terror group ISIS had issued a chilling video threatening more attacks, saying: "What you witnessed in Bangladesh was a glimpse. This will repeat, repeat and repeat until you lose and we win and the sharia is established throughout the world."The Bangladesh government has denied that international jihadist networks have gained a foothold in the country. It said the Dhaka attack was carried out by the members of a local banned Islamist group.
