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)

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".
