Artwork inspired by the al-Qaeda leader Osama Bin Laden is one of the four pieces nominated for this year's £40,000 Turner Prize.
Langlands and Bell's work has been shown at the Imperial War Museum
The four artists on the shortlist are Kutlug Ataman, Jeremy Deller, Langlands and Bell and Yinka Shonibare.
The installation of video and photos from Afghanistan by Langlands and Bell is called The House of Osama Bin Laden.
Past Turner nominees have attracted controversy. Last year's prize was won by transvestite potter Grayson Perry.
Kutlug Ataman, a Turkish artist who lives in the UK, is nominated for his "poignant and incisive video installations".
His work was shown at the Istanbul Biennial last year, and he has also been shown at other European venues.
Jeremy Deller is shortlisted for Memory Bucket, which is a video installation based in the US city of San Antonio. It shows the artist's journeys through the state of Texas.
Turner Prize organisers said the work was a "personal investigation of the social and cultural make-up that defines different societies".
Kutlug Ataman is a Turkish-born artist who creates DVD installations
Yinka Shonibare is a London artist who was born to Nigerian parents, and spent much of his childhood in Nigeria.
He uses African fabric in his work, which has included the exhibition Double Dutch at the Museum Boijmans Van Beuningen, Rotterdam.
Langlands and Bell - artists Ben Langlands and Nikki Bell - travelled to Afghanistan after the fall of the Taleban regime in 2001.
They visited several sites, including the former home of al-Qaeda leader Osama bin Laden, in Daruntah, west of Jalalabad. He had lived there for a time in the late 1990s.
Their work was captured on a still and video camera.
During their Afghanistan trip they also visited the American airbase at Bagram, a murder trial at the Supreme Court in Kabul, the site of the statues of Buddha at Bamyan demolished by the Taleban.
Last year's winner Grayson Perry wore a dress at the 2003 awards ceremony
The exhibition has already been exhibited at the Imperial War Museum in London, and also in Dublin.
The shortlisted works will be exhibited at Tate Britain from 20 October to 23 December, with the winner announced on 6 December.
The prize is open to any artist under the age of 50 who is either working in the UK or is British and working abroad.
Past winners have included Gilbert and George, Anish Kapoor, Antony Gormley and Damien Hirst.
The success of transvestite potter Grayson Perry in 2003 maintained the award's reputation for controversy.
The 43-year-old potter - who is married with a young daughter - turned up to the ceremony wearing a £2,500 pink dress.
Perry said he believed his new status would allow him the opportunity to turn down work he would previously have taken on.
"It gives me power," he said. "I'm not very good at saying no, and this will get the 'no' muscle into shape," he said last year.
