The first of many Alexandrias in the Far East of the Macedonian Empire, Alexandria in Ariana was a city in what is now Afghanistan, one of the twenty-plus cities founded or renamed by Alexander the Great.
 The third largest Afghan city, Herat, is the city's modern name.
Kabul (Pashto/Dari: کابل‎ ‎ , "Kâbol", ] ; ) is the capital of Afghanistan as well as its largest city, located in the eastern section of the country.
 According to latest estimates, the population of the city is about 4.6 million, which includes all the major ethnic groups.
 Rapid urbanization had made Kabul the world's 64th largest city and the fifth fastest-growing city in the world.
The Battle of Boz Qandahari occurred on November 3, 2016, in the village of Boz Qandahari, on the western outskirts of the Afghan city of Kunduz, between Afghan National Security Forces, Resolute Support Mission forces, and Taliban insurgents.
The El Ayyat train disaster happened at 02:00 on the morning of 20 February 2002 in an eleven-carriage passenger train travelling from Cairo to Luxor.
 A cooking gas cylinder exploded in the fifth carriage, creating a fire which engulfed seven third-class carriages, reducing them almost to cinders.
 The initial number of dead given by officials at the time was 383, all Egyptians.
 However, considering that seven carriages were burnt to the ground, and each carriage was packed with at least double the maximum carrying capacity of 150, this number is considered by many people to be a great underestimate.
 The dubious nature of the given death toll lies with the absence of a full passenger list; accounting for those missing was almost impossible at the time.
 In addition, the fire was so intense and the carriages so badly burned that many corpses had been reduced to ash.
 As there was no means of communication between the driver and the rear carriages, the driver did not know of the fire until about two hours after it had begun, resulting in many people, attempting to flee from the overcrowded carriages, jumping to their death.
 Some important Egyptians have commentated that the official number of 383 dead is grossly inaccurate and was an attempt to lessen the damage done to the reputation of the government.
 Many people consider a number of about 1000 deaths to be more accurate.
The 2001 uprising in Herat was a coordinated insurrection and uprising in the Afghan city of Herat as part of the United States war in Afghanistan.

HMS "Kandahar" (F28) was a K-class destroyer built for the Royal Navy during the 1930s, named after the Afghan city of Kandahar.
The Siege of Herat (1837-1838) was an unsuccessful attack on the Afghan city of Herat, by the Qajar dynasty of Persia, during the time of the Great Game.
