Bangladesh police shot dead an Islamist militant Wednesday, the fourth killed since a crackdown was launched against suspected jihadists blamed for a wave of gruesome killings, an officer said. The 25-year-old militant was killed during a gun battle with police in northern Bogra district, where he was suspected of bombing a minority Shiite shrine last year, the officer said. Kawser, known by one name, was the fourth member of the local Jamayetul Mujahideen Bangladesh (JMB) killed, with three "high-ranking" members of the Islamist militant group shot dead Tuesday during raids in Dhaka and a north-western district.
