Gavin Williamson said that Britons who had gone to Syria or Iraq to fight for Islamic State hated what Britain stands for, and that air strikes could be used against the estimated 270 British citizens who are still out there, Hindustantimes reported.
“Quite simply my view is a dead terrorist can’t cause any harm to Britain,” Williamson told the Daily Mail in an interview published late on Wednesday.
“We should do everything we can do to destroy and eliminate that threat,” he said, adding that he believed any British fighters who joined Islamic State should never be allowed to return to the United Kingdom.
Williamson, 41, has been defence minister for little over a month, replacing Michael Fallon after he quit in a sexual harassment scandal.
Prominent British militants such as Mohammed Emwazi, known as Jihadi John, and Sally Jones, have been reportedly killed by British or U.S. forces since travelling to fight for Islamic State.
After the death of Jones, who was known as the “White Widow”, Fallon said that British nationals who chose to leave the UK and fight for Islamic State were a “legitimate target”.
