The British general Charles Gordon was killed there in 1885 while the city was under siege by Sudanese followers of a religious leader called the Mahdi. The city was won back from the Mahdi forces in 1898 by General Herbert Kitchener. .) Khartoum became the capital of the Anglo-Egyptian Sudan in 1899 and remained the country's capital after it gained independence in 1956. In August 1998 a chemical factory in Khartoum with alleged ties to an international terrorist was bombed by the United States.
