Sistan

Region in Asia

Sistān, also known as Sakastān and Sijistan, is a historical region in present-day south-eastern Iran, south-western Afghanistan and extending across the borders of south-western Pakistan. Mostly corresponding to the then Achaemenid region of Drangiana and extending southwards of the Helmand River not far off from the city of Alexandria in Arachosia. Largely desert, the region is bisected by the Helmand River, the largest river in Afghanistan, which empties into the Hamun Lake that forms part of the border between Iran and Afghanistan.
