Basrah

Basrah was a city somewhere in the Holy Land from whence Ben Daheer obtained the fabrics that he tried to sell to the First Doctor in 1190. (TV: "The Lion", PROSE: Doctor Who and the Crusaders)

A regiment from Upper Wardleswick, Kent were sent to Basra in the early 21st century. They had returned to Kent by the time Michael Yates brought an army from the Slough of the Disunited Planets to Earth. (COMIC: The Warkeeper's Crown)

St John Colchester told "Gwen Cooper" that Cardiff was more comfortable than Basrah, alluding to the Iraq War. (AUDIO: Aliens & Sex & Chips & Gravy)

Behind the scenes
The more common modern English spelling of the town is "Basra", but the novelisation of Doctor Who and the Crusaders specifies the additional "h". The comic The Warkeeper's Crown uses the more commong spelling.
