Khartoum
The city proper has a population of well over a million, but forms with its neighbours Khartoum North (al-Khartûm Bahrî) and Omdurman (Umm Durmân) a metropolis totalling now probably over four million inhabitants.
Troops loyal to the Mahdi Muhammad Ahmad laid siege to Khartoum starting on March 13, 1884 and captured the city, defended by General Gordon, on January 26, 1885. Omdurman was the scene of the bloody battle (September 2, 1898) in which British forces destroyed the Mahdist army defending the city.
Following the 1998 U.S. embassy bombings, the United States, accusing Osama bin Laden's Islamic extremist al-Qaeda group of responsibility, retaliated with cruise missile attacks (August 20) on al-Qaeda camps in Afghanistan and the al-Shifa pharmaceutical factory in Khartoum.
