Pashtuns are spread over a wide geographic area, south of the Amu river and west of the Indus River. They can be found all over Afghanistan and Pakistan.[1] Big cities with a Pashtun majority include Jalalabad, Kandahar, Bannu, Dera Ismail Khan, Khost, Kohat, Lashkar Gah, Mardan, Ghazni, Mingora, Peshawar, Quetta, among others. Pashtuns also live in Abbottabad, Farah, Herat, Islamabad, Kabul, Karachi, Kunduz, Lahore, Mazar-i-Sharif, Mianwali, and Attock.[citation needed] The city of Karachi, the financial capital of Pakistan, is home to the world's largest urban community of Pashtuns, larger than those of Kabul and Peshawar.[2]
