At least 12 people were killed and 100 wounded in a bomb attack on Saturday on an opposition rally in Bangladesh's capital, police and witnesses said. Former Bangladesh Prime Minister Sheikh Hasina Wajed had been addressing the crowd and her Awami League party said the blasts, possibly caused by grenades, were an assassination attempt on her. She escaped with minor injuries. The attack was the latest in a series in impoverished Bangladesh and the second deadly blast this month against the Awami League. A party leader was killed in the northeastern town of Sylhet two weeks ago. "After one blast, I was lying in the street. Then, I heard seven or eight more blasts and something hit me in the head and I fainted," said an Awami League worker with a bandaged head after the Dhaka attack, giving his name only as Gaisuddin. Reuters reporters at a government hospital where the injured were taken counted nine dead bodies from the blast site, including two women, lying in the hospital. --more 2318 Local Time 2018 GMT
