Afghanistan: insurgents held without charge by British forces However, Mr Hammond said it was "patently ridiculous" to link the internment of the men to Guantanamo, as Britain is only holding insurgents because it fears the Afghans would not treat them properly. Speaking on the Today programme, he also said those held are suspected of trying to kill British troops and pointed out their lawyers are being funded by UK legal aid. Mr Hammond said parliament was well aware that insurgents were detained by British forces and criticised the lawyers involved for failing to express concern for British soldiers.
